Compulsory Task 1 ●くろまる 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.

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this...

Java requires its method arguments to be sent in as values, not references. And what, precisely, does it entail?

Write a code in Java programming You are working in a game company that is developing a new RPG game. One of the core features of the game is the ability to create and manage different types of characters, such as warriors, mages, and archers. However, your colleague, who was previously working on the implementation of the CharacterManager class, has been laid off due to excessive absences. You have been assigned to take over the project and complete the implementation of the class based on the design specifications outlined below: Given the following main method: public static void main(String[] args) { CharacterManager manager = CharacterManager.getInstance(); manager.createCharacter(CharacterType.WARRIOR).attack(); manager.createCharacter(CharacterType.MAGE).attack(); manager.createCharacter(CharacterType.ARCHER).attack(); } Your output should be: Warrior is attacking Mage is attacking Archer is attacking Note that you should not change the method signature.

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); } }...
