Question

1.Create full program in Java that will simulate a Rock Paper Scissors Game You will create the code so that when the program is run the user will see in the console the following: We are going to play rock paper scissors. Please choose 1 for Rock 2 for Paper or 3 for scissors. The program will have your choice which is the integer-valued typed in by the user and compChoice which will be the randomly generated value of either 1 2 or 3. You will test all the ways the user wins if he or she beats the computer using || with if and then you will check all the ways that computer could win using else if with || and lastly the only other thing that can happen would be a tie if both choices are the same for the default else. Display what was chosen and what was randomly chosen by the computer and who wins or if there is a tie. For extra credit, you can use dialog boxes and show images.

Hi, I Hope you are doing will.

Below is the program for ROCK PAPER AND SCISSORS Game

import java.util.*;

class Game 
{
    
    public static final String ROCK = "ROCK";
    public static final String PAPER = "PAPER";
    public static final String SCISSORS = "SCISSORS";

    public static void main(String args[]) 
    {
      System.out.println("Enter any of the following inputs:  ");
      System.out.println("1 for ROCK");
      System.out.println("2 for PAPER");
      System.out.println("3 for SCISSORS");
      System.out.println();
          
      String playerMove = getPlayerMove();
      String computerMove = getComputerMove(); 
 
      /*if both playerMove and computerMove
        produces the same formation, then 
        Game is tie*/
      if (playerMove.equals(computerMove))
            System.out.println("Game is Tie !!");
      // if player's Move is ROCK and input is 1         
      else if (playerMove.equals(Game.ROCK))
        System.out.println(computerMove.equals(Game.PAPER) ? "Computer Wins": "Player wins");   
      // if player's Move is PAPER and input is 2
      else if (playerMove.equals(Game.PAPER))
        System.out.println(computerMove.equals(Game.SCISSORS) ? "Computer Wins": "Player wins");   
      // if player's Move is SCISSORS and input is 3
      else
        System.out.println(computerMove.equals(Game.ROCK) ? "Computer Wins": "Player wins");   
    }
    
    /* Get Computer's move using Random method */   
    public static String getComputerMove()
    {
        String computermove;
        Random random = new Random();
        int input = random.nextInt(3)+1;
        if (input == 1)
            computermove = Game.ROCK;
        else if(input == 2)
            computermove = Game.PAPER;
        else
            computermove = Game.SCISSORS;
            
        System.out.println("Computer move is: " + computermove);
        System.out.println();
        return computermove;    
    }
    
    /* Get Player's move using Scanner
       class */
    public static String getPlayerMove()
    {
        Scanner in = new Scanner(System.in);
        int playermove = in.nextInt();
        System.out.println("Player move is: "+playermove);
        if(playermove == 1)
        return "ROCK";
        else if(playermove == 2)
        return "PAPER";
        else
        return "SCISSORS";
    }    
}

OUTPUT:
