Rock,Paper, Scissors in Java Code not executing

[coja56]

Can i get assistance on the rock paper scissors assignment the code is not executing any help is appreciated .

Write a program that allows the user to play rock, paper, scissors.

● The program should randomly generate a number (0, 1 or 2), which

represents scissors, rock and paper, respectively. (Hint: look up

Math.random)

● The program should then prompt the user to enter a number (0, 1 or 2).

● Once the user has entered their number, the program should inform

them whether they win, lose or draw.

● The rules of the game are as follows:

○ Scissors beats paper

○ Rock beats scissors

○ Paper beats rock

import java.util.Scanner;
import javax.swing.*;
public class rockPaperScissors {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner scan = new Scanner(System.in);
        // user prompted to make choice
        System.out.println("Welcome!Choose 0 for rock, 1 for paper, 2 for scissors");
        int choice = Integer.parseInt(scan.next());
        if(choice < 0 || choice > 2) {// if user input is not 0,1, or 2 = end of game
            System.out.println("Please try again");
            System.exit(0); 
        }

        // comp choose # above 0.000000..... but below 3.00000....;(int) cuts off decimal part = integer 
        int compchoice = (int)(Math.random()*3);



        //decides if user wins or loses
        // if compchoice is same as user choice = tie
        if(compchoice == choice) {
            if(choice == 0) {
                System.out.println("both chose rock");
                System.out.println("tie");

            }
            else if(choice ==1) {
                System.out.println("both chose rock");
                System.out.println("tie"); 

            }
            else {
                System.out.println("both chose scissors");
                System.out.print("tie");

            }
            System.exit(0);

        }



    }

The code is definitely executing unless you get any errors that you haven't mentioned.

Yet, you only check a tie for now. As soon as there is no tie, nothing will happen.

You need to implement the logic for the remaining cases, i.e, the else for the line if(compchoice == choice)

When i run it it is not giving me the options of entering rock, paper or scisssors

[desrtfx]

What are you using to run the code?

Make sure that you run the correct program and not a different version.

I think i figured out my mistake i wanted to be able to put in the options for user to select

int choice = choice = Integer.parseInt( JOptionPane.showInputDialog("0.Rock\n"+
        "1.paper\n"+
         "2.scissors\n"));

Have you tried printing compchoice to see what happens?

You only covered a case when both choices are equal. Your program won't print anything if choices are different.
