i don't quite know what you mean but here is what i'm guesing you want:
import javax.swing.*;
import java.util.Scanner ;
import java.util.Random;
import java.awt.FlowLayout;
import javax.swing.event.DocumentListener;
import javax.swing.event.DocumentEvent;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.*;
class rps extends JFrame implements ItemListener, ActionListener {
public static void main(String args[]){
new rps();
}
JLabel l1 = new JLabel("choose rock, paper or scissors");
JLabel l2 = new JLabel();
JLabel l3 = new JLabel("vs");
JLabel l4 = new JLabel();
JLabel l5 = new JLabel();
JComboBox c = new JComboBox();
JButton b = new JButton("go!");
static void Sleep1000(){
try{
Thread.sleep(3000) ;
} catch (InterruptedException e){
System.out.println("program ended") ;
}
}
public rps(){
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) ;
setLayout(new FlowLayout()) ;
add(l1);
add(l2);
add(l3);
add(l4);
add(l5);
l3.setVisible(false);
add(b);
b.addActionListener(this);
b.setEnabled(false);
add(c);
c.addItem("");
c.addItem("rock");
c.addItem("papper");
c.addItem("scissors");
c.addItemListener(this);
pack();
setVisible(true);
}
public void itemStateChanged(ItemEvent e){
b.setEnabled(true);
c.setEnabled(false);
}
public void actionPerformed(ActionEvent e){
int op = new Random().nextInt(2)+1;
int po = op;
b.setEnabled(false);
if(c.getSelectedItem().equals("rock")){
l1.setVisible(false);
l3.setVisible(true);
l2.setText("rock");
if(po == 1){
Sleep1000();
l4.setText("paper");
Sleep1000();
l5.setText("you lose");
}else{
Sleep1000();
l4.setText("scissors");
Sleep1000();
l5.setText("you win!");
}
}
if(c.getSelectedItem().equals("paper")){
l1.setVisible(false);
l3.setVisible(true);
l2.setText("paper");
if(po == 1){
Sleep1000();
l4.setText("scissors");
Sleep1000();
l5.setText("you lose");
}else{
Sleep1000();
l4.setText("rock");
Sleep1000();
l5.setText("you win!");
}
}
if(c.getSelectedItem().equals("scissors")){
l1.setVisible(false);
l3.setVisible(true);
l2.setText("scissors");
if(po == 1){
Sleep1000();
l4.setText("rock");
Sleep1000();
l5.setText("you lose");
}else{
Sleep1000();
l4.setText("paper");
Sleep1000();
l5.setText("you win!");
}
}
}
}
hope that helps

Hi, I just created a simple Rock, Paper, Scissors program. Here's the code I used. Sorry the comments are limited and sorta crappy.

Code:

import java.io.*;
import java.util.*;

class RPS {
	String UserRPS;		// The Users choice
	String CompRPS;		// The Computers choice
	
	int countWins;
	int countLoses;
	
	public RPS() throws IOException {
		BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		
		System.out.println("This program is a game of Rock, Paper, Scissors with the computer.");
		System.out.println("Type exit to end the game.");
		
		while(true) {
			System.out.println("The game is currently " + countWins + " Wins and " + countLoses + " loses.");
			System.out.println("Type in R for Rock, P for Paper, and S for Scissors.");
			UserRPS = in.readLine();
			UserRPS = UserRPS.toUpperCase();
		
			CompRPS = ComputerRPS();
		
			if(UserRPS.equals("R")) {	// The logic used for if the user wins or loses,
				UserRock();		// depends on what the user entered.  Use these
			}				// if statements to choose the correct logic for 
			if(UserRPS.equals("P")) {	// the UserRPS.
				UserPaper();
			}
			if(UserRPS.equals("S")) {
				UserScissors();
			}
			if(UserRPS.equals("EXIT")) {
					break;
			}
		}
	}
	
	public String ComputerRPS() {			// This method determines the 
		int CompChoice;				// computer choice for Rock, Paper
		String CompRPS = "";			// or scissors.  This is determined
							// randomly.
		CompChoice = (int)((Math.random() * 2) + 1);
		
		if(CompChoice == 1) {
			CompRPS = "R";
		}
		if(CompChoice == 2) {
			CompRPS = "P";
		}
		if(CompChoice == 3) {
			CompRPS = "S";
		}
		return CompRPS;
	}
	
	public void UserRock() {			// This method is used for 
		if(CompRPS.equals("R")) {		// when the user chooses Rock.
			System.out.println("The computer chooses Rock. The game " +
				"is a draw.");
		}
		if(CompRPS.equals("P")) {
			System.out.println("The computer chooses Paper. You lose X(.");
			++countLoses;
		}
		if(CompRPS.equals("S")) {
			System.out.println("The computer chooses Scissors. You win ;).");
			++countWins;
		}
	}
	
	public void UserPaper() {			// This method is used for 
		if(CompRPS.equals("R")) {		// when the user chooses Paper.
			System.out.println("The computer chooses Rock. You win ;).");
			++countWins;
		}
		if(CompRPS.equals("P")) {
			System.out.println("The computer chooses Paper. The game is a draw.");
			
		}
		if(CompRPS.equals("S")) {
			System.out.println("The computer chooses Scissors. You lose X(.");
			++countLoses;
		}
	}
	
	public void UserScissors() {			// This method is used for 
		if(CompRPS.equals("R")) {		// when the user chooses Scissors
			System.out.println("The computer chooses Rock. You lose X(.");
			++countLoses;
		}
		if(CompRPS.equals("P")) {
			System.out.println("The computer chooses Paper. You win ;).");
			++countWins;
			
		}
		if(CompRPS.equals("S")) {
			System.out.println("The computer chooses Scissors. The game is a draw.");
			
		}
	}
}

public class TestRPS {
	
	public static void main(String[] args) throws IOException {
		RPS rps = new RPS();
		System.out.println("Thanks for playing.");
	}
}
