Question

Write a do-while loop IN JAVA to build a Pokémon game

Prompt the user for two names one for their Pokémon, and one for the computers Pokémon

Make two integer variables to hold the HP of each Pokémon, HP should be 20 for both Pokémon’s.

Use Math.random() to determine the amount of damage caused, and which move the computer will select. The range of damage that can be done is up to you.

Output to the user an attack menu with different moves

In a do-while loop, prompt the user to pick an attack for their Pokémon to perform.

Store the damage in a variable and deduct points off the computer’s Pokémon HP.

Be sure to print out the name of the attack and the amount of damage that was imposed. For example: “Pokemon 1 used kick, and did 3 damage”

Use a random number to randomly pick an attack for the computer.

Use a random number to deduct points off the user’s pokemon HP.

Make sure to print out the computer's moves and the damage inflicted when it does an attack

Be sure you are checking the health points of each Pokémon at the end of each loop.

When the loop exits, indicate whether the user or computer won the game.

Dear student,

Here is the game coded using JAVA programming language:

CODE:

import java.io.*;
import java.util.*;

public class Main
{
        public static void main(String[] args) {
            Scanner sc=new Scanner(System.in);//used for input
            
            //For printing the attack menu
            System.out.println("Hello User. Here is the names of your attacks, their damage and code");
            System.out.println("KICK, DAMAGE:3, CODE: 0");
            System.out.println("PUNCH, DAMAGE:4, CODE: 1");
            System.out.println("BUMP, DAMAGE:2, CODE: 2");
            System.out.println("SPECIAL ATTACK, DAMAGE:8, CODE: 3");
            
            String poke1="";//for user's Pokemon
            String poke2="";//for computer's pokemon
            
            int hp1=20;

            System.out.println("Enter the name of your Pokemon");
            poke1=sc.nextLine();
            System.out.println("Enter the name of Computer's Pokemon");
            poke2=sc.nextLine();
                
                
            do
            {
                //User's turn to attack
                System.out.println("Pick an attack to perform and enter its code");
                int attack=sc.nextInt();
