6 Interesting Ideas from Research Papers about Java

There are a lot of research papers related with Java. If we type “Java programming”, there are more than a million result in Google scholar. Some papers are very theoretical, some seem to be practical. I recently found some ideas are pretty interesting, so I collect them and create a list. These papers are from world top software engineering conferences.

1. Automatically Insert Blank Lines to Improve Code Readability

As a coding convention, programmers use blank line to separate different logical sections in a Java method. When a method does not contains blank lines, the technique presented in this paper can insert blank lines.

Paper Link 1 , Paper Link 2

2. Automatically Identify One of the Most Common Idioms – Loops-If

Code idioms are code fragments that recur frequently across software projects and have a single semantic purpose. This paper detect loops that contains a single if, such as the following:

for (Iterator<RepoSource> it=mSources.iterator(); it.hasNext(); ) { RepoSource s=it.next(); if (s.isUserSource()) { it.remove(); } }

Such a structure does 12 common things, such as find an element, count, filter, etc. If the idea is implemented, old version Java might be migrated to Java 8 Stream API automatically.

3. Mine idioms from source code

This paper presents a technique which automatically retrieve all common code idioms. It is interesting to see that one of the most common idioms is:

Document doc=Jsoup.connect(URL). userAgent("Mozilla"). header("Accept","text/html"). get();

Of course, the result depends on what open source projects they use for the mining purpose.

4. Mine Code Examples from Open Source Projects

The technique presented in this paper can recommend code examples based on context. I always hope there is a tool that can recommend the next line based on the code that has already been typed. Hopefully such a tool can come out of research lab soon.

5. Generate Comment for Source Code by Using Stack Overflow

Comments improve program comprehension and software maintainability. It is beneficial to generate code comments automatically. In this paper, they propose a general approach to generate code comments automatically by analyzing existing open source projects and Stack Overflow posts. They discover similar code and use the description on Stack Overflow to describe the other similar code segments.

6. Generate Comment from Source Code

Comments improve program comprehension and software maintainability. This paper summarizes the comment generation work.

Those ideas are pretty cool. Hopefully they can release their implementation soon.

Design and Implementation of Information System Based on Java Technology Platform

Design & implementation of enhanced security architecture to improve performance of cloud computing.

Cloud computing offers various features such as creates, configure and customize application online. User can access applications over the Internet and they can also access database via Internet. Open nature and public access make their application vulnerable for several security attacks. This paper attempt to integrated different previously defined security approaches to propose a new and novel model of security. Here, proposed solution approach to improve performance of confidentiality, authentication, integrity and access control with better and strong way. Proposed solution is implemented using java technology and evaluated based on computation time and memory consumption. A detailed comparison with graph is also demonstrated in experimental analysis section.

Empirical Assessment of the Quality of MVC Web Applications Returned by xGenerator

Many scholars have reported that the adoption of Model Driven Engineering (MDE) in the industry is still marginal. Real-life case studies, completed with convincing empirical data about the quality of the developed source code, is an effective way to persuade the industry that the adoption of MDE brings an actual added value. This paper reports about the assessment of the quality of the code outputted by xGenerator: a Java technology platform for the development of enterprise Web applications, which implements the MDE paradigm. Two recent papers from Aniche and his colleagues were selected to carry out the measurements. The former study is about metrics and thresholds for MVC Web applications, while the latter presents a catalog of six smells tailored to MVC Web applications. A big merit of both of these proposals is that they fix the metric thresholds by taking into account the MVC software architecture. The results of the empirical assessment, carried out on a real-life project, proved that the quality of the code is high.

Application of Java Technology in Dynamic Web Database Technology

Hybrid news recommendation system using tf-idf and similarity weight index.

As the usage of internet is increasing, we are getting more dependent on it in our daily life. The Internet plays an essential role to simplify our tight schedules. In such tough lives, it is very important to stay aware of current affairs. Now for different people coming from different backgrounds and professions, the preferences are different too. Here come Data mining techniques in the picture, which gives us “Recommender system” as the output, capable of delivering more relevant and worthy outcomes. Newspapers are the basic obligation asked by almost every person to stay updated and aware of the world. But as we observe that nowadays, various solutions are been developed to convert paper news system to digital news and raise the bar of the quick news. And that’s how News Recommender systems are have made an important place in our fast running lives.This research paper has investigated the News Recommendation solution right from its core, including the importance, performance, and improvement suggestions. This paper talks about enhancing the performance of states solution by using modified Term Frequency-Inverse Document Frequency (TF-IDF) algorithms. Proposed solution advocates the usage of JAVA technology which reflects fruitful results in the final graphs of accuracy, precision, and F-score. Here, BBC dataset has been used for comparison study purposes.

Application of Java Technology in Industrial Real-time Systems

Marine biological monitoring and managing system based on java technology, design and implementation of app system for legal consulting based on java technology, online-calculator “a calculation of baking formula” for automated workplace of operator-technologist.

Calculation of recipes of dough for bakery products is a significant and routine operation. Doughing is the main stage of technological process in bakery production. The quality of both the dough and the final product is caused by baking properties of flour and also a ratio of water, yeast, salt, sugar and cooking fat. The recipe of a bakery product is developed for the purpose of its production with the required properties due to assigned amount of components. Development of the automated calculator for calculation and correction of the recipes of bakery products is explained by the bakery technologist’s daily need in calculating the amount of components. Basic data for calculation are type, quantity and humidity of the main (flour, grain products) and additional components (sugar, butter, cocoa and others), amount of flour which is used for preparation of ferment. The technique of calculation of recipes of fermented dough and non-fermented dough is considered. There are panels for the choice of a way of doughing, for setting the amount of flour and grain products, and other components, setting additional data, and the result of calculation of recipes. The data found during the calculation of the recipe of bakery products come to the database and are used for controlling the recipes, for proper dosing. The programming language JavaScript with jQuery library is chosen. Programming is carried out in free source code editor Notepad++ The source code editor developed on the basis of Java technology has a number of advantages for industrial consumers. The main advantages are independence of the hardware platform and the operating system. Besides, development of the automated online calculator accessible on any personal computer connected to Internet network simplifies considerably the technologist’s work.

Design and Implementation of University Art Education Management System Based on JAVA Technology

Along with the popularity of teaching ideas such as quality-oriented education and comprehensive education, colleges and universities are paying more attention to the art teaching and art training of students. Besides, the rapid development of computer technology and its extensive penetration in many fields promote the de-velopment of art teaching management model towards standardization and sche-matizations. Therefore, a university art teaching management system based on JAVA technology is designed. The system chooses JAVA as the main pro-gramming language, eclipse as the development tool, and SSH of Open Source as the basic framework. MVC pattern is used to design the Struts architecture to en-sure the data processing capability of the system, and SQL is used as the backend database to ensure the integrity of the data and the storage efficiency of the sys-tem. After testing, the system meets the expected requirements, changes the tradi-tional university art teaching model, and enriches the dimension of art teaching. What’s more, the system expands the thinking of art teaching work for teachers in colleges and universities, and also satisfies the urgent demand of university students for art training.

Key takeaways.

  • Java 11 has reached parity with Java 8 in terms of market share.
  • Quarkus, introduced after Micronaut and Helidon, continues to be a popular framework and has "crossed the chasm" into the Early Majority space.
  • Containers have broken through and are now the way that the majority of Java applications are deployed.
  • Microsoft furthers its commitment to Java with the release of their own downstream distribution of OpenJDK and having joined the Java Community Process. Microsoft Build of OpenJDK is a new participant in the OpenJDK downstream distribution space.
  • Spring Framework 6 and Spring Boot 3, scheduled for GA releases in 2022, will be a major overhaul of these projects to adopt modularity. Spring Native has emerged as a new tool to convert existing Spring Boot applications, written in Java or Kotlin, to GraalVM native images.
  • MicroStream has emerged as a new participant in the Java ecosystem.
  • After years of stagnation, VS Code is shaking things up in the Java IDE space.

This article provides a summary of how the InfoQ Java editorial team currently sees the adoption of technology and emerging trends within the Java space.

We focus on Java the language, as well as related languages like Kotlin and Scala, the Java Virtual Machine (JVM), and Java-based frameworks and utilities.

We discuss trends in core Java, such as the adoption of new versions of Java, and also the evolution of frameworks such as Jakarta EE , Quarkus , Micronaut , Helidon , MicroProfile and MicroStream .

This report has two main goals:

  • To assist technical leaders in making mid- to long-term technology investment decisions.
  • To help individual developers in choosing where to invest their valuable time and resources for learning and skill development.

This is our third published Java trends report. However, this topic has received ample news coverage as we have been internally tracking Java and JVM trends since 2006.

To help navigate current and future trends at InfoQ and QCon, we make use of the “crossing the chasm” mental model for technology success pioneered by Geoffrey Moore in his book of the same name. We try to identify ideas that fit what Moore referred to as the early market, where “the customer base is made up of technology enthusiasts and visionaries who are looking to get ahead of either an opportunity or a looming problem.”

As we have done for the 2020 and 2019 Java trend reports, we present the internal topic graph for 2021:

For context, here is our internal topic graph for 2020

Aside from some new technologies having been identified in the Innovators space, notable changes include: defining versions of Spring (and their related projects), Jakarta EE and Scala into different categories. We decided on this approach to avoid generalizing these technologies into one category when varying degrees of maturity and adoption exist.

Spring Framework 6 and Spring Boot 3, scheduled for GA releases in late 2022, will be going through an overhaul to adopt modularity and will require JDK 17+ and Jakarta EE 9. A preview has recently been made available with the first milestone release of Spring Framework 6.

Introduced at the beginning of 2021, Spring Native is a new tool to convert existing Spring Boot applications, written in Java or Kotlin, to GraalVM native images and is in the very early stages of development.

Scala 3, released earlier this year , was overhauled with many new features, new syntax and the much-anticipated new Dotty compiler that has been under development for a number of years.

Earlier this year, Microsoft furthered their commitment to the Java programming language when they introduced Microsoft Build of OpenJDK, their own downstream distribution of OpenJDK.

AdoptOpenJDK joined the Eclipse Foundation and was immediately renamed Adoptium. The transition to Adoptium included the creation of an Eclipse Working Group and a split of AdoptOpenJDK into multiple sub-projects under the Adoptium top level project: Eclipse AQAvit , Eclipse Temurin and Eclipse Temurin Compliance .

What follows is a lightly-edited summary of the corresponding discussion on various topics among several InfoQ Java Queue editors and Java Champions:

  • Michael Redlich , Senior Research Technician at ExxonMobil Research & Engineering and Java Queue Lead Editor at InfoQ
  • Ben Evans , Senior Principal Software Engineer at Red Hat, Java Champion and Java Queue Editor at InfoQ
  • Erik Costlow , Director of Developer Relations at Contrast Security and Java Queue Editor at InfoQ
  • Johan Janssen , Software Architect at Sanoma Learning and Java Queue Editor at InfoQ
  • Karsten Silz , Senior Full-Stack Java Developer and Java Queue Editor at InfoQ
  • Monica Beckwith , Senior Principal Engineer at Microsoft and Java Champion
  • Ana Maria Mihalceanu , Developer Advocate at Red Hat and Java Champion
  • Reza Rahman , Principal Program Manager for Java on Azure at Microsoft
  • Simon Ritter , Deputy CTO at Azul and Java Champion

We feel this provides more context for our recommended positioning of some of the technologies on the internal topic graph.

Beckwith : Java is now a more vigorous enforcement of OOP principles via JEP 403: Strongly Encapsulate JDK Internals . Vector computation via a platform-agnostic Vector API. The language additions, such as Records, and JVM improvements, such as project Valhalla, remove many verbosities and further embrace the concept of immutability, thus providing opportunities for performance optimizations.
Mihalceanu : This year pleasantly surprised Java developers with both LTS and non-LTS Java releases. The Java 17 release was the confirmation that many of those preview features are now generally and long-term available. It also added a sense of urgency for some projects that still run on Java 8 to migrate to a newer version. Java 17 is the LTS that fulfilled the lifelong dream of having helpful NullPointerExceptions.
Rahman : As always, all parts of the Java ecosystem remain lively. This speaks to the fundamental strength of Java. I think Java SE 17 has been particularly well received, especially features like Records. Runtimes like WildFly, Payara and Open Liberty are adopting Java SE 17. While some developers have adopted Java SE 11, Java SE 8 remains remarkably sticky. It is possible Java SE 17 will finally change that.
Ritter : The release of JDK 17 has been significant. This means developers now have a new long-term support (LTS) release from all the OpenJDK distributions. For those not wishing to upgrade their Java version every six months to remain as stable and secure as possible, this is an important release. I like the way that we are seeing more small language features added to the platform more quickly than we've ever seen before. This is thanks to the six-month release cadence, which also makes both incubator modules and preview features practical. There are also some interesting developments in how the JVM can work in a cloud environment such as the new project in OpenJDK called co-ordinated restore at checkpoint (CRaC). Features, like records, are great for developing new code.
Evans : The release of Java 17 LTS, and the ability to finally start deploying code that leverages Records and Sealed Types, as well as JFR Streaming for monitoring groups of JVMs. The path towards standardization in the Observability space - especially OpenTelemetry. Early signs of a consensus emerging around what it means for Java to be statically deployed ("Static Java"). I also think Panama will be a bigger deal than people expect.

Downstream Distributions of OpenJDK

Costlow : There are too many non-differentiated JDK distributions out there now. Microsoft has one, Eclipse has Adoptium with Temurin, Oracle has theirs and an OpenJDK build, Azul, AWS Corretto, Red Hat, Liberica, SAP Machine, etc. I'm seeing a proliferation of these, but it's hard to keep them straight. Snyk's  survey  seemed relatively in line with what I see in terms of usage. Given that they're all compatible, I'd like to see a "Just get me OpenJDK" randomizer in the marketplace to remove a decision for new junior Java devs. The Eclipse branding in particular is confusing: Adoptium is a group inside Eclipse, which is also a group. Temurin is the thing you use and it is OpenJDK. Imagine learning Java on your own and reading this sentence: "Eclipse Temurin is the name of the OpenJDK distribution from Adoptium." Fewer brand names is better.
Janssen : Liberica, which is from Bellsoft, actually offers quite some interesting products which differentiate them from other JDK vendors. For instance, a full JDK which still contains JavaFX. I only know of ojdkbuild which offers a similar build. Next to that, they have more variants of the JDK and the JRE. Azul supports non-LTS versions with minor updates for a longer period of time. Some vendors offer Docker images, etc. So there are some differences, but it's hard for end users to compare them and make a good decision about which one to select.

Java EE/Jakarta EE

Rahman : The transition from Java EE to Jakarta EE is one of the largest and most significant technology transfers in our space. That is finally on solid ground with Jakarta EE 9.x. It is very good to see how Jakarta EE 10 is now progressing towards a release early next year. It looks like many of the items in the Jakarta EE Ambassador's Contribution Guide are materializing, closing some long-standing gaps. I think this is a big relief to long term Java EE users. I am also very happy to see Jakarta EE 9.x building momentum. Most runtimes have adopted the javax to jakarta namespace transition including Tomcat and Jetty. Spring Framework 6 is committed to adopting both Java SE 17 and Jakarta EE 9. Similarly, MicroProfile 5 is transitioning to Jakarta EE. According to the 2021 Jakarta EE Developer Survey , a substantial number of developers have already transitioned to the jakarta namespace or are planning to do so. The Jakarta EE 10 Core Profile is paving the way for Quarkus and Helidon becoming fully compatible, the MicroProfile Config API is transitioning to the new Jakarta Configuration specification and the same is happening with MicroProfile Context Propagation. It is possible the same will happen with the MicroProfile REST Client and JWT Propagation.
Redlich : With the release of Jakarta EE 9, tooling vendors can support the new jakarta package namespace, development teams can test migration of their applications to the new namespace, and runtime vendors can test and deliver options and capabilities that support migration and backwards compatibility with Jakarta EE 8. Jakarta EE 9 may also be considered a foundation for innovation to drive new features in Jakarta EE 10 and beyond.

GraalVM/Spring Native

Mihalceanu : Building a native executable is another topic often marked as “most wanted” as the race for smaller, faster containerized applications continues.
Rahman : It is also very good to see that Spring Native is making progress.
Costlow : I like seeing the role of native apps taking shape, but disappointed by the lack of an actual specification or working group. It seems to be kind of "you get whatever GraalVM happens to do" and it behaves differently at times than a standard JDK - similar but not the same.
Janssen : Spring Native competes with all the GraalVM and other frameworks with fast startup times and low memory usage.
Silz : Once Spring Boot supports native compilation with GraalVM, fast and small native Java programs will go mainstream. This makes Java more competitive for serverless solutions and may help it in the microservices arena. I say "may" because as of today, I think that the JVM JIT still has better throughput/performance for long-running processes than GraalVM. Either way, that'll get a lot of press and make Java more competitive overall.

ARM64/Windows on ARM

Beckwith : ARM64 is now commodity hardware. As a result, the presence of Java development kits and the Java runtime environments optimized for deployment on ARM64 have gained mainstream popularity.
Silz : Java 16 supports Windows on ARM. But I think only Java 17 with ARM on macOS will blow the doors wide-open. I believe about a quarter of all Java developers use Macs. And by the end of 2022, they can only buy Macs with ARM. I expect that this will push both Windows and Linux on ARM to get better, too.

Jakarta EE and MicroProfile Alignment == Cloud Native for Java

Redlich : The MicroProfile and Jakarta EE Working Groups, two complementary initiatives under the auspices of the Eclipse Foundation, have collaborated to form a Cloud Native for Java (CN4J), an alliance to define Jakarta EE and MicroProfile positioning and alignment, both branding and technical for cloud-native technologies.
Rahman : It is a pleasant surprise to see Quarkus making well-earned headway with both Java EE and Spring developers. It is also very good to see Jakarta EE and MicroProfile alignment finally happening.

JavaFX/Gluon

Costlow : I am extremely impressed at the work that Gluon is doing to make a single JavaFX codebase run across everywhere. Web was the missing piece from before and, frankly, client Java now seems cool again.

Adopting Modularity

Silz : I think that JPMS tries to solve three problems: class loading woes for app servers; better structuring of the JDK and all Java applications; and reducing the JVM footprint for deployment/runtime. But at least when JPMS finally launched after multiple delays, there were good enough solutions for these problems already: OSGI for class loading; Domain-Driven Design/Clean Architecture/Modulith/ArchUnit tests for Java program structure; and ahead-of-time compilation for reduced JVM footprint. As few unreliable data points we may have, they all show usage of Java 8 and older either being greater than or equal to that of Java 11 and later. I think this is partly because modules gave Java 9+ the reputation of being "hard to upgrade to from Java 8," as Mark Reinhold acknowledges . That's an unintended consequence of JPMS. And it means that at least half of all Java developers can't use the Java advances of the last seven years because they're stuck on Java 8. The opportunity cost of working on modules for probably 7+ years means that many other Java improvements either fell to the wayside or only appeared in Java 10 and later. The var keyword for variables, the new switch syntax, and Java records reduce a lot of the boilerplate that Java's infamous for. If those were in Java 9 instead of Java modules, I think Java would be in a better place now because it had better developer productivity.

What Has Changed Since Last Year?

Beckwith : Many architects and developers have tamed the GC (garbage collection) pause times due to the improvements to the existing collectors. Many others have tamed the tail latencies by transitioning to low-latency, adaptive GCs for their workloads.
Evans : Java 11 has essentially reached parity with Java 8 in terms of market share. Containers have broken through and are now the way that the majority of Java apps are deployed. Quarkus continues to mature and gain ground and new fans.
Redlich : A few Eclipse Foundation Working Groups have been established: MicroProfile, OSGi and Adoptium (formerly known as AdoptOpenJDK). The MicroProfile Working Group and the Jakarta EE Working Group have collaborated on a Cloud Native for Java (CN4J) Alliance initiative. Microsoft furthers its commitment to Java by creating its own downstream distribution of OpenJDK, Microsoft Build of OpenJDK, and by joining the Java Community Process.

What is the Java Community Saying?

Beckwith : Pattern matching for switch statements, native image, cloud native-JVM, and JVM on accelerators, project Loom and Graal.
Mihalceanu : Upgrading. Because the Java language evolved, framework features flourished as well. In my experience, writing clean and secure code promptly depends on the practices shared by a team. Nowadays, it is possible to minimize the time spent developing or fixing code with continuous testing and fewer local configurations thanks to some framework built-in capabilities.
Rahman : Java SE 17 and Quarkus are enjoying the limelight. Kubernetes remains wildly popular. There is early enthusiasm around Spring Native. Folks in the open standard Java community are watching Jakarta EE 10 and MicroProfile/Jakarta EE alignment closely. There is something good happening pretty much for everyone in the ecosystem.
Ritter : The focus for pretty much all developers, at least when working on new development, is how to make the most effective use of the cloud, especially through a microservice architecture. Leveraging containers and technologies like Kubernetes and Spring Boot are very powerful when writing these types of applications. I hear a lot of discussion about how to use these.
Evans : Java 17, Loom, Quarkus.

What’s New and Exciting That We Didn’t Expect?

Beckwith : I had anticipated the richness of the Java ecosystem and the different JDK vendor flavors of the Java Dev Kits offerings. Still, the sheer participation and the agreement towards the accelerated release cadence were a welcome surprise.
Mihalceanu : What I love about Java is that each release adjusts both the language and the experience of developers. Enhancements such as the new date formatter for period-of-day introduced in java.time.format.DateTimeFormatter and DateTimeFormatterBuilder classes, pattern matching with switch, or the default method toList() in java.util.stream.Stream interface help developers to write cleaner and easier to read code.
Ritter : Looking at the Java platform, there wasn't anything we didn't expect and that's a good thing. Now that new features use JEPs to define what they are intended to do, we have a clear roadmap of the things that will be included in Java looking some years into the future. This means developers can be comfortable that there are not going to be big changes that impact backwards compatibility, at least not without plenty of time to evaluate and discuss them.
Evans : A new focus on warm start / suspend-and-resume / CRaC technologies from a number of providers, including Azul and Red Hat.
Redlich : The emergence of MicroStream, a Java persistence company. While their history goes back to 2013, the company was formally founded in 2019. Since then, they open-sourced MicroStream earlier this year with the release of MicroStream 5.0 and has collaborated with MicroStream has been integrated with Helidon and has just released version 6.0.
Silz : After years of stagnation, VS Code is shaking things up in the Java IDE space. It's something new: A cross-platform, cross-language IDE that's fast, has great plug-ins, and is loved by its users! If that sounds like "Eclipse IDE 20 years ago", you're right! VS Code recently boosted its Java capabilities. I expect it to become the best free Java IDE. I think Eclipse recognized that threat and created a Working Group to coordinate a defense. I'm not sure how much IntelliJ will be affected. One exciting side effect of using VS Code for Java development is that you can easily develop with non-JVM languages. I don't think you can do that in Eclipse at all, or only in a limited way. You can develop with non-JVM languages using JetBrains "All Products Pack", but then you have to launch different IDES that don't share settings, plug-ins, or keyboard shortcuts.

The Java Community

Mihalceanu : I started my Java journey while in university, learning that Java supports Object-Oriented Programming with design patterns and coding best practices. As a professional, I am happy to see that throughout the time, the language has embraced other paradigms as well: functional, reactive thus giving more implementation options without losing the readability. How to choose between each model? Occasionally profile your application, spot bottlenecks, and improve your implementation logic. Yet, no advancement is possible without people. The Java Community is large, vibrant, and welcoming, present both physically and virtually all for one purpose: to share knowledge, improve ourselves, and succeed when facing problems.

Please note that the viewpoints of our contributors only tell part of the story. Different parts of the Java ecosystem and locales may have different experiences. Our report for 2021 should be considered as a starting point for debate, rather than a definitive statement, and an invitation to an open discussion about the direction the industry is taking.

Although Java is a relatively new programming language ( it was launched in the early 1990s ), it has created a unique niche in the IT industry. Java is the driving force behind some of the largest organizations, including Airbnb, Uber, eBay, Pinterest, Groupon, Spotify, Intel, Symantec, TCS, Infosys, Wipro, Flipkart, and TripAdvisor, to name a few.

As an OOP language, Java has a modular structure, making solving complex problems significantly easier. Thus, programmers can write reusable codes with Java, enhancing the development process. Additionally, Java offers various features, such as polymorphism, abstraction, inheritance, and encapsulation, that further simplify the code-writing process. Easy to program and run, Java-based applications can be developed to operate on one computer as well as multiple client and server systems within a network.

The five main reasons for Java’s popularity are:

  • Platform independence – Java runs on the WORA (Writing Once, Run Anywhere). A Java code is compiled into an intermediate format (a.k.a. bytecode), which is then executed in the JVM (Java Virtual Machine). So, any system running a JVM can execute Java code. Furthermore, JRE (Java Runtime Environment) is compatible with all three operating systems – Linux, macOS, and Windows.
  • Multi-threaded – Java has inbuilt multithreading capabilities, which means that you can develop highly interactive and responsive apps with multiple concurrent threads of activity using Java.
  • Object-oriented – Java is a purely object-oriented language. Inspired by C and C++, Java extends the functionality of these languages to become a pure object-oriented programming language. Abstraction, encapsulation, inheritance, and polymorphism are some of its core OOP features. 
  • Secure – When it comes to safety, Java incorporates a host of safety features into the runtime systems, including runtime checking and static type-checking at the time of compilation. With these features in place, it is pretty challenging to hack into a Java application from an external source.
  • Robust – Java leverages a simple memory management model reinforced by automatic garbage collection. Since Java objects do not require external references, Java code is robust. Besides, it also encourages developers to adopt productive programming habits for developing secure and reliable applications. The more you experiment with different java projects, the more knowledge you gain.
  • Open source – Java’s position as the second most trending programming language worldwide ( IEEE Spectrum ) in 2023 primarily rests on it being freely available for use; in other words, it is open source. This makes it ideal for developers and programmers of various competencies looking to build apps of their own. They can even access the latest versions of Oracle JDK and Open JDK free of charge through the Java Development Kit.
  • API rich – Consisting of approximately 52 keywords, Java boasts a rich and extensive API (Application Programming Interface). Thus, making projects in Java is easy, with a multitude of methods available for use in any program directly. Developers can accomplish any task with Java API methods, whether handling output input, networking, processing XML, or connecting to databases.
  • Community backup – Java’s robust and active community is among the many reasons for its continuing popularity. The Java Community, Stack Overflow, and Java in General are some of the top communities where developers and beginners alike can find assistance when faced with a problem. If you are developing core Java projects or seeking project ideas for Java, you can find extensive and reliable support on these websites from expert developers.
  • Documentation support – Another factor contributing to Java’s immense popularity is its detailed documentation feature. Javadoc, a well-documented guide, provides solutions to developers who face problems while coding any application or program.
  • Development tools – In addition to frameworks, integrated development environments (IDE), and profilers, Java has an arsenal of various automation, debugging, and editing tools. Java has tools for every type of development project along with various stages of development. Different projects in Java require the use of different tools. These include Maven for building applications, Jenkins for integration and delivery, JIRA for bug tracking and planning, and Splunk for monitoring, to name a few.
  • User-friendly – Java offers an easy learning curve with its simple English syntax and use of minimum special characters. This makes it easy for beginners and professionals to master this language. Basic knowledge of programming languages like C and C++ is all that is needed to learn Java and build projects using Java later. Resources are readily available online on various websites, mostly for free.

  • Admin module – The Admin uses this module to check information on the manufactured products, newly launched products, and products that must be delivered to the clients.
  •  Dealer module – This module keeps track of all the essential information concerning the dealers, particularly the record of items. Dealers can generate and update the item list for a product using this module. 
  • Client module – The client uses this module to provide the necessary specifications of a product. The client feedback is processed through this module and forwarded to the Admin. 

By using this application, the clients can directly convey their product requirements to the manufacturer, who then contacts multiple vendors to acquire the necessary resources for making the product. The dealers usually create a list of items as per the product information provided to them, after which the manufacturer selects the materials that best fit the specifications given by the client.

Then, the selected list of items is forwarded to the inventory department for processing, after which the manufacturing begins. Once the production is complete, the accounts department calculates the raw materials costs and manufacturing costs to generate the total bill. Finally, the product, along with the invoice, is shipped to the client. The client is free to offer feedback on the received product.

17. Virtual private network

java research paper ideas

VPN is one of the trending java projects. The goal of building this virtual private network (VPN) is to extend a private network across a public domain (for example, the Internet). A VPN is created by setting up a point-to-point virtual connection via traffic encryption, dedicated connections, or virtual tunneling protocols.

There are three interconnected modules in this VPN project: 

  • Administration module – This module monitors all the office operations and manages the staff details. 
  • Marketing module – This module handles everything related to the marketing operations of the software application.
  • Training module – This module manages all the technical operations like software testing, networking, call center, and J2EE training.

Confidentiality, authentication, and data integrity are the three core elements of this VPN security model. The other pivotal features of this application are:

  • It allows for the addition of new clients, a feature better known as “scalability.” This feature allows a company/organization to accommodate new clients in the network as it expands. 
  • It uses a remote backup server to prevent the system from failing due to sudden crashes. Since a VPN handles a large volume of files that are created every day, it is crucial to have a remote backup server to process all the requests coming from the client to the server and vice-versa.
  • It uses a remote monitoring system to keep track of the activities of every client or individual connected to the VPN. This ensures that the privacy and security of the network remain intact.
  • As is true of all VPNs, this VPN application, too, has the provision for certification in the system. When two or more LAN (Local Area Network) systems interact, certification is mandatory to protect the system’s security. 
  • It triggers and sends acknowledgment signals to notify clients of successful data transfer (whether or not the data has successfully reached the desired destination).

18. ATM simulation system 

Among the most user-oriented Java mini projects for engineering students , an ATM simulator offers an easy and effective way to deposit and withdraw money and check account balance. It is based on the command-line user interface, where a switch case executes all transactions (withdrawal and deposit) and balance checks. Each operation is followed by an instant account update, helping customers keep track of their transactions.

The system comprises two aspects — admin mode and user mode. The admin side allows the bank’s staff to register a new account, update existing accounts, delete obsolete accounts, and view user account records. Whereas, the user mode allows customers to perform transactions to another account, withdraw money, print receipts, and check balance. 

Key features of the ATM simulator system are as follows:

  • 24*7 banking service
  • Reduced human error
  • Banks will receive notification about any impending maintenance of ATM
  • Constant updation of bank records reduces backlogs in the system
  • Enhanced security between bank servers and customers
  • Improved customer service 

19. Customer relationship management system

The CRM system is designed with the aim to assist businesses in keeping digital records of all customer interactions. If you are considering Java projects for final year , this project is the best choice. It provides the source code for Java and uses the Spring framework. The project requires sound knowledge of MySQL, JSpring framework, Java database connectivity, and HTTP. 

This application aims to help businesses improve customer satisfaction by providing access to past, present, and potential customer data and help maintain them efficiently. CRM systems operate by collecting customer data from various sources like the company’s website, live chats, social media, telephone, emails, etc.

This mini project in Java is an open-source desktop application consisting of 3 main roles — admin, user, and employee. The primary user is the admin, who can change product-related details like adding, deleting, and updating. They can also change the FAQs and keep track of user history, employee details, complaints, inquiries, etc. 

Employees can access complaints, inquiries, and product lists and also keep profiles updated with information collected from emails, calls, and chats. This reduces the time to resolve customer issues, enhancing the overall customer experience.

Conversely, users can view product details, raise complaints, view FAQs, and make service/product-related inquiries.

Some advantages of the CRM system are:

  • Build a robust and secure CRM application.
  • Drive customer engagement
  • Contains records of users, employees, complaints, resolutions, and more.
  • Provide error-free application

20. E-magazine

This is among the simplest Java mini projects . In this project, a platform is created mimicking an online magazine. In other words, an e-magazine offers the facilities and features of an online magazine, providing users with international and national news and articles categorized distinctly into separate sections.

With the advent of digitization, many publishers have shifted to the internet to provide digital versions of their printed magazines and journals. Some companies have entirely quit publishing printed versions to cut production costs and adopt more environment-friendly policies. Users of an e-magazine are generally classified into 2 categories — guests and paid users. Guests have access to only some features of the magazine, while paid users are given full access in exchange for a subscription fee.

This mini project in Java consists of 2 modules:

  • User Module- Allows customers to log in, read the magazine, post comments, publish advertisements, and submit articles.
  • Editor Module- Allows editors or the publisher to create new articles or content, edit articles, and see the magazine preview before publishing.

A few advantages of e-magazines are mentioned below:

  • Saves paper, making way for a more environmentally aware society.
  • Reduces cost significantly, thus increasing profit margin for publishers.

21. Mobile tracking system

Of all the Java project topics , this one ranks among the top useful application ideas. Mobile phones are no longer used for luxury but have become a necessity in the modern world. With violent incidents becoming commonplace, safety concerns have increased manifold in the last couple of years. This is where Java mini projects like this come in handy. 

As the name suggests, the mobile tracking system tracks the present location of a user’s phone. This web application is developed on MySQL database using PHP. It constantly updates the location of the chosen device every five seconds through a central tower. The system sends the server the mobile ID and location, along with the time the device was present at the location.

The system has to be installed in the chosen device, following which each device is assigned a unique ID. This ensures you can track the desired mobile phone from anywhere, anytime. This project aims to boost security and consists of two primary components: the web application (serves as the admin) and mobile tracking software installed on the phone to be tracked. 

22. Currency converter application

If you are looking for Java mini projects for beginners, this is the perfect application for you to try your hand at. This simple project serves the purpose of converting different currency denominations.

Ajax is used to build this simple calculator-based application, and it offers a web-based interface. This project is equipped with a regular updation feature that enables it to keep up with the changing exchange rates. The app contains two fields, both denoting some currency. The user has to select the currency they want to convert and the one they want to convert into and then enter their preferred amount.

The app is extensively used in finance-related fields, businesses, and stock markets where currency exchange and transfer are done regularly.

feature_pencilpaper

One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

113 Good Research Paper Topics

Below are 113 good research topics to help you get you started on your paper. We've organized them into ten categories to make it easier to find the type of research paper topics you're looking for.

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.

Java Frameworks You Must Know in 2024

Irina Mariasova

Many developers trust Java worldwide because it is adaptable, secure, and versatile, making it perfect for developing various applications across multiple platforms. It also stands out for its readability and scalability.

What are frameworks? Why do you need them?

Since Java has a long history, there are plenty of frameworks and libraries to streamline your Java development process.

They provide pre-made chunks of code and a set of rules on how to build your app. This means you don’t have to start from zero every time you want to create something; you can use these tools to help you along, making it faster and easier to get your app working

In this article, we’ll look at the most popular, efficient, and trending Java frameworks that can help you level up your code.

Spring Framework and Spring Boot

Since the early 2000s, Spring has evolved alongside Java to provide efficient tools for building Java applications for projects ranging from small-scale web apps to large, complex systems. Spring is not just a framework. It’s an entire ecosystem of supporting frameworks and tools that cover almost all aspects of application development and ensure your application can be developed, tested, and scaled efficiently.

Where to Use Spring

You can use Spring in various areas, including web and enterprise development, microservices, data management, cloud-based applications, big data processing, automation, and testing.

Cool Features

Here is a list of the most powerful capabilities that Spring has to offer

Dependency Injection . Spring lets you inject dependencies either through constructors or setters, making your code neater and more organized.

Spring MVC : This is a popular Java framework used for building web applications. It follows the Model-View-Controller (MVC) architectural pattern that separates the application into three main parts: model, view, and controller.

Spring Boot : This is a sub-project of Spring that allows you to create stand-alone, ready-for-production Spring applications with minimal setup and configuration.

Transaction Management : Spring gives you a consistent way to manage transactions across different APIs like JTA, JDBC, Hibernate, JPA, and JDO.

Spring Data : This makes building applications with Spring and data access technologies more efficient.

Spring Security : A powerful framework that provides strong and customizable security measures for your Spring applications, including authentication and access control.

Testing Support : Spring offers great tools for unit and integration testing, including libraries like JUnit, Mockito, and more.

IntelliJ IDEA provides full Spring support . IntelliJ IDEA has Spring Initializr integration which allows you to create a new Spring project in just a few clicks right from the Welcome screen. What’s more, our IDE provides advanced coding assistance for Spring, including navigation, validating configurations, displaying autowired beans, etc.

Micronaut 

Micronaut is a JVM-based framework used for developing microservices or serverless applications. It’s designed to provide the tools and infrastructure for building scalable, high-performance applications with minimal memory footprint and startup time. The framework supports the Java, Kotlin, and Groovy languages. Micronaut shares some similarities with frameworks like Spring, yet it stands out for its unique features.

Where to Use Micronaut

It is excellent for developing microservice-based applications and is also useful in cloud environments like Docker and Kubernetes.

Dependency injection happens at compile time instead of runtime, as in most frameworks. This method, unlike the traditional use of reflection and proxies, allows you to start the application faster and reduce memory usage.

Reactive programming support supports reactive programming models, making it easier to handle asynchronous data flows and concurrency.

Extensive integration provides seamless integration with a variety of databases, cloud services, and other tools, offering flexibility in application development.

Hibernate is an open-source Object-Relational Mapping (ORM) framework for Java applications. It’s designed to simplify the development of data-driven applications. Hibernate has its own language, Hibernate Query Language (HQL), which uses objects instead of table names. Thanks to HQL, Hibernate can significantly reduce development time, make your code less error-prone, and easier to understand and maintain than raw SQL. 

Where to Use Hibernate

Hibernate can be used in any Java application that interacts with a relational database. 

Cool Features 

Lazy Loading : Your data is retrieved only when called, saving memory and improving performance.

Cache Mechanism : This mechanism allows frequently used data to be stored in memory, which reduces database load and speeds up data retrieval in your application.

Reduced Boilerplate Code : With Hibernate, you don’t have to write tedious JDBC code for CRUD (create, read, update, delete) operations. It manages the database operations in the background, thus reducing your development time.

IntelliJ IDEA offers coding assistance for Hibernate, such as autocompletion for HQL queries, handy inspections and quick-fixes, and the Hibernate console that allows you to run your HQL queries straight from the IDE.

Apache Kafka 

While not a framework, Apache Kafka is an essential open-source stream processing platform for handling large amounts of data in real time. We consider it to be a very helpful asset for Java developers as it can scale up effortlessly without any downtime, making it great for managing big data projects.

Combining the various Kafka APIs for publishing or subscribing to one or more Kafka topics and the Kafka Streams API to implement stream processing gives you a good foundation for building scalable, decoupled applications.

Where to Use Kafka

Kafka is great for handling live data and constantly updating applications. It’s used on websites to track what users are doing and also in systems that need to share data between different parts.

Decoupling : Apache Kafka helps systems and data streams work independently and asynchronously. This can be explained through basic terms. Kafka uses topics to organize data streams. Producers send messages to the topics without needing to know who will consume them and don’t wait for a consumer to be available. Consumers subscribe to topics and handle messages at their own speed without blocking the producer if it’s processing messages slowly.

Fault tolerance in Apache Kafka means that even if something goes wrong, like a server crashing, Kafka can keep running without losing data. It does this by making copies of data and automatically switching to backups if needed.

Integration with other systems : Kafka can integrate with a wide range of systems, including databases, file systems, stream processing frameworks, etc.

IntelliJ IDEA offers the Kafka plugin , which allows you to monitor your Kafka event streaming, make consumers, producers, and topics, and connect to Schema Registry to create and update schemas.

JUnit 5 is a popular Java framework used for writing and running automated tests to check if your code is working as expected. JUnit 5 helps keep your code neat and readable, find and fix errors, boost software quality, and improve testing efficiency.

Where to Use JUnit 5

JUnit is predominantly used for unit testing of individual units of Java code (like methods or classes) in isolation from the rest of the application.

Annotations . JUnit 5 annotations serve as special markers in Java code, offering

instructions to the JUnit 5 framework on test execution. For instance, @Test marks a method as a test method, while @Disabled skips the annotated test method during execution. @DisplayName allows you to write a display name for your test in a normal sentence.

Assertions are the methods that verify that your code behaves as expected.

Test runners are special programs that allow you to run tests and see the results, telling you which tests passed or failed.

Test suites : This feature lets you group several tests and run them together.

Parameterized tests allow you to run the same test multiple times with different sets of parameters, making sure the functionality works for different inputs.

Nested tests : The @Nested annotation in JUnit 5 allows you to group several test methods within nested classes inside a main test class, helping to organize tests more clearly and adding expressiveness to your tests, making them easier to read and understand.

IntelliJ IDEA is fully integrated with the JUnit framework. To create a test for a specific class, you can simply right-click on it, select Create test , and choose JUnit 5 as a desired testing library. Running tests is also straightforward and easily accessible from the UI. It’s that simple!

Mockito 

Mockito is a popular mocking framework for unit tests in Java. It allows you to create mock objects in automated unit tests that mimic the real objects in your tests. For instance, if your code needs to fetch data from a database, Mockito allows you to set up a mock database that returns the required test data, so you don’t have to use the actual database. 

Where to Use Mockito

You can use Mockito in unit tests to isolate code units by mocking their dependencies.

Automated mock creation : You can create mocks with the @Mock annotation to reduce boilerplate code in your tests. 

Spying allows you to use real objects in your tests, calling all their methods except the ones you choose to stub. 

Methods stubbing : Stubs define how a mocked method should behave when invoked. For example, you can make a method return a specific value or throw an error when tested. This helps you check how your code works in different situations without using the actual methods.

ArgumentCaptor lets you capture and examine an argument passed to a method, which is very helpful when the argument isn’t accessible outside the method you’re testing.

WireMock is another framework that can help you create stubs and mocks. However, this time, the framework simulates HTTP-based APIs. It acts as a real web server that is capable of providing stubbed responses to a client’s requests.

Where to Use WireMock

Use WireMock when you want to test your application’s interaction with external HTTP services, during the development of a microservice that depends on other services, or to create detailed logs for debugging complex issues, without having to use those actual services.

Fault Simulation : WireMock allows you to simulate problems such as delays, connection resets, and random noise, mimicking an unreliable server or network. 

Request Matching : It is possible to match incoming requests by URL, HTTP method, headers, and body content to determine the appropriate response.

Record and Playback : It is capable of recording requests to a real service and then playing them back, which is useful for creating mocks based on actual service behavior.

Starting from version 2024.1, IntelliJ IDEA comes with the WireMock plugin.

Testcontainers 

Testcontainers is another framework for testing your application. It focuses on integration testing, which checks how different parts of an application work together. It is designed for situations where you need to write integration tests with other services that should be running during your tests.

Where to Use Testcontainers

Testcontainers is ideal for integration tests and for testing the full flow of an application in an environment that imitates production setup. 

Test isolation guarantees that your tests will not affect each other’s data.

Support for various technologies : Testcontainers supports databases like MySQL, Postgres, MongoDB, and others. It also works with Selenium browser environments for end-to-end tests, and message brokers like RabbitMQ, Kafka, etc.

Easy integration with JUnit allows you to effortlessly add tests that use containers to your current tests. 

Automatic clean-up : Testcontainers removes everything it uses, like containers, volumes, or networks, after the tests are done. This keeps your testing space tidy and helps avoid resource leaks.

You can use Testcontainers in IntelliJ IDEA with your test framework of choice, for example with JUnit.

Awaitility is a small open-source Java DSL library that simplifies testing asynchronous systems. This means that it lets the tests wait until an asynchronous operation finishes or a specific condition is met, which is very helpful for testing concurrent systems.

Where to Use Awaitility

Use Awaitility when writing tests that include asynchronous operations, such as:

  • Ensuring actions are completed within a specific time frame.
  • Testing web services or similar systems where responses can be delayed.
  • Checking conditions in multithreaded or concurrent systems within a defined period.

Timeout: Awaitility allows you to set a timeout for a specific condition in a test. If the condition isn’t met within this time limit, it stops the test, preventing it from running forever.

Custom conditions : Beyond just using timeouts, you can create specific conditions for more flexible testing in various scenarios. 

DSL Syntax : Offers an easy, explicit syntax for specifying conditions, making tests easier to understand and maintain.

Jackson is a comprehensive library for reading, writing, and manipulating JSON data in Java applications. With its help, you can parse JSON to Java objects and serialize Java objects to JSON.

Where to Use Jackson

Jackson is highly versatile and can exchange data over RESTful APIs, persisting Java objects to JSON files, and processing external JSON data. 

Java annotations support : Jackson allows developers to use Java annotations extensively, giving them significant control over the serialization and deserialization processes.

Streaming API : It offers a fast, efficient method to read and write JSON, which is ideal for handling large JSON files or data streams with minimal resource usage.

Support for various data formats : Jackson can work with various data formats such as JSON, XML, CSV, and YAML.
