Compulsory Task 1 ● Follow the instructions above on how to debug a program using Eclipse. Create a simple calculator application that asks a user to enter two numbers and the operation (e.g. +, -, x, etc.) that they'd like to perform on the numbers. Display the answer to the equation. Every equation entered by the user should be written to a text file. Use defensive programming to write this program in a manner that is robust and handles unexpected events and user inputs.

Q1. Write two Java classes for calculating the power m" using the recursive method as follow: Class A A. Define two private variables in the class: names n and m. B. Define a constructor takes two parameters m and n and assign them to the class variables. C. Define setter and getter methods. D. Define a recursive method which take two parameters n, m and calculates the power using recursion. Class B: A. Define the main method. B. Define an object of class A and call its constructor which takes two parameters C. Call all the defined methods in Class A. Send the values 4,5 when call the recursion method.

Java Language I want to round up the answer. How to use it in java?   public static double calculateBMI(double height, double weight) {return 703 * weight / (height * height);}

For the code in java below it shows a deck of 52 cards and asks the name of the two players and makes both players draw five cards from the deck. What I want to be added onto the code is the possibility for Player A too chose whatever card they want from his/her 5 cards and Player B has to chose two cards from his/her 5 cards that equal in value of Player A's card.  I also want the cards that have been used to be replaced by different cards in the deck of 52 cards and that game to go on until the deck runs out of cards. Main class code: import java.util.ArrayList; import java.util.Scanner; import java.util.List; import java.util.Random;   class Main { publicstaticvoid main(String[] args) { // card game, two players, take turns. String[] suits = {"Hearts", "Clubs", "Spades", "Diamonds"}; String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};   for(String oneSuit : suits){ for(String num : numbers){   System.out.println(oneSuit + " " + num);     } }…
