Need Help With Java Rock Paper Sissors Code


Question

I am writting a rock paper scissors program for my java class. I have wrote a program that should work but i keep having trouble with getting my variables to work write. Sometimes compiler will read them and sometimes it wont. I am using jgrasp to write with. Any help would be greatly appreciated. Also this is my first time using java so i know there are some mistakes. I just cant find them.

import javax.swing.JOptionPane;

import java.util.Random;

public class RockPaperScissors

{

public static void main(String[] args)

{

JOptionPane.showMessageDialog(null, "Let's play Rock Paper Scissors.\n1 = Rock\n2 = Paper\n3 = Scissors");

String player;

player = JOptionPane.showInputDialog("Please Enter a number between 1 and 3.");

Random generator = new Random();

int computer = 1 + generator.nextInt(2);

boolean case1, case2, case3, case4, case5, case6, case7, case8, case9;

case1 = (player = 1) && (computer = 2);

case2 = (player = 1) && (computer = 3);

case3 = (player = 2) && (computer = 1);

case4 = (player = 2) && (computer = 3);

case5 = (player = 3) && (computer = 1);

case6 = (player = 3) && (computer = 2);

case7 = (player = 1) && (computer = 1);

case8 = (player = 2) && (computer = 2);

case9 = (player = 3) && (computer = 3);

if (case1)

JOptionPane.showMessageDialog(null, "Computer choses Paper. You lose.");

else if (case2)

JOptionPane.showMessageDialog(null, "Computer choses Scissors. You win.");

else if (case3)

JOptionPane.showMessageDialog(null, "Computer choses Rock. You win.");

else if (case4)

JOptionPane.showMessageDialog(null, "Computer choses Scissors. You lose.");

else if (case5)

JOptionPane.showMessageDialog(null, "Computer choses Rock. You lose.");

else if (case6)

JOptionPane.showMessageDialog(null, "Computer choses Paper. You win.");

else if (case7)

JOptionPane.showMessageDialog(null, "Both choose Rock. Tie.");

else if (case8)

JOptionPane.showMessageDialog(null, "Both choose Paper. Tie.");

else if (case9)

JOptionPane.showMessageDialog(null, "Both choose Scissors. Tie.");

System.exit(0);

}

}

case1 = (player == 1) && (computer == 2);

Thank you but jgrasp still stops at case1. It now says

??RockPaperScissors.java:18: error: incomparable types: String and int

?ϧ? case1 = (player == 1) && (computer == 2);

?ϧ? ^

The human player is providing a number when asked - but the data type returned by that function is actually a String. You need to convert that string into an Integer to successfully compare it to the computer's selection (which is an integer).

See Integer.parseInt
