Rock, paper, scissors

[StevenF]

Hey there, I'm new to Java and made a simple rock, paper, scissors program using Random() and if-else. Just curious as to whether or not there are different ways of doing it (I'm sure there are, but this is what I came up with).

// Rock, paper, scissors program that will ask for input
// then compare to random choice by computer

import java.util.Scanner;
import java.util.Random;

public class RockPaperScissors {

	public static void main(String[] args) {

		// Rock Paper and Scissors as Static Values
		int ROCK = 0;
		int SCISSORS = 1;
		int PAPER = 2;
		
		// Variable intChoice for comparing to randomInt
		int intChoice = 4;
		
		// New Scanner
		Scanner key = new Scanner(System.in);
		
		System.out.print("Please enter rock, paper, or scissors: ");
		String choice = new String(key.nextLine());
		
		if (choice.compareToIgnoreCase("rock") == 0)
			intChoice = ROCK;
		else if (choice.compareToIgnoreCase("paper") == 0)
			intChoice = PAPER;
		else if (choice.compareToIgnoreCase("scissors") == 0)
			intChoice = SCISSORS;
		else 
			System.out.println("You must enter either rock, paper, or scissors.");
			

		// New random generator
		Random randomGenerator = new Random();
		int randomInt = randomGenerator.nextInt(3);
		
		if (intChoice == randomInt)
			System.out.println("Tie!");
		else if (intChoice == 0 && randomInt == 1)
			System.out.println("Rock beats scissors! You win!");
		else if (intChoice == 0 && randomInt == 2)
			System.out.println("Paper covers rock... You lose.");
		else if (intChoice == 1 && randomInt == 0)
				System.out.println("Rock beats scissors... you lose.");
		else if (intChoice == 1 && randomInt == 2)
				System.out.println("Scissors cuts paper! You win!");
		else if (intChoice == 2 && randomInt == 0)
			System.out.println("Paper covers rock! You win!");
		else if (intChoice == 2 && randomInt == 1)
			System.out.println("Scissors cuts paper... You lose.");
		else 
			System.out.println();
		
		
	}

}

EDIT: Small fix when entering something other than rock, paper, or scissors.

This is overkill, but you could always use a payoff matrix a la Game Theory.

It's a good idea to declare your constants as final, and to have them outside the body of the main method.

Thanks, forgot about that.
