Question

We would like to know how to make a rock paper scissor game.

Answer

import java.util.Random;
/* w  w w .j  av a  2s  .c o  m*/
enum Gesture {
  rock(1), paper(2), scissors(3);

  private int type;

  Gesture(int type) {
    this.type = type;
  }

  public int getType() {
    return type;
  }
}

public class Main {
  public static void main(String[] args) {
    String choice = "S";

    if (choice.equals("S")) {
      generateDraw(Gesture.scissors);
    } else if (choice.equals("R")) {
      generateDraw(Gesture.rock);
    } else if (choice.equals("P")) {
      generateDraw(Gesture.paper);
    }

  }

  public static void generateDraw(Gesture gesture) {
    final Random random = new Random();
    final int computerDraw = random.nextInt(3);
    System.out.println(computerDraw);

    if (computerDraw > gesture.getType()) {
      System.out.println("You lose.");
    } else if (computerDraw < gesture.getType()) {
      System.out.println("You win.");
    } else {
      System.out.println("It is a tie.");

    }
  }
}

The code above generates the following result.
