Your task is the following:

§     Given a user input `n`, print the output in the given format, if `n` = 1,  print:

o     byte_array[1] = ‘P’

§   private double x;

§   private double y;

and methods:

§   public Point(double x, double y){}  // Constructor to create a new point?

§   public double distance(Point p2){} // Function to return the distance of this Point from another Point

Week 9 : Programming Assignment 5

Complete the code below with a catch statement to print the following if the denominator (b) is zero

§   Cannot Divide by ZERO

Week 10 : Programming Assignment 1

Week 10 : programming assignment 2, week 10 : programming assignment 3.

• The  PrintNumbers  class is declared, and it implements the  Runnable  interface. This interface is part of Java's concurrency support and is used to represent a task that can be executed concurrently by a thread.
• Create a constructor of this class that takes two private instance variables (start and end) to represent the range of numbers that will be printed by the thread.
• Create a  run  method that is required by the Runnable interface and contains the code that will be executed when the thread is started. In this case, it should prints odd numbers within the specified range (start to end) using a for loop.
• Hints : Thread.currentThread().getName() returns the name of the currently executing thread, which is useful for identifying which thread is printing the numbers.

Week 10 : Programming Assignment 4

Week 10 : programming assignment 5.

• Use exception handling to handle invalid input temperatures (if  celsius < -273.15 and fahrenheit < -459.67 , program should throw exception error).
• The  TemperatureConverter  class contains two methods for temperature conversion (celsiusToFahrenheit and fahrenheitToCelsius).
• The  TemperatureException  class is a custom exception class that extends Exception and is used to handle invalid temperatures.
• The  TemperatureConverterApp  class is the main class that takes user input for temperatures and handles potential exceptions during the conversion process.
• celsiusToFahrenheit = (celsius * 9 / 5) + 32
• fahrenheitToCelsius = (fahrenheit - 32) * 5 / 9
