I recommend that you look at using an ImageIcon and place that icon into a JLabel. Then you can use a CardLayout to swap JLabels when necessary. You can find out more about this plus some great sample code here:

How to Use Labels (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Swing Components)
How to Use Icons (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Swing Components)
How to Use CardLayout (The Java™ Tutorials > Creating a GUI with JFC/Swing > Laying Out Components Within a Container)

Also, one more thing: when posting code here, please use code tags so that your code will retain its formatting and thus will be readable -- after all, your goal is to get as many people to read your post and understand your code as possible, right?

To do this, highlight your pasted code (please be sure that it is already formatted when you paste it into the forum; the code tags don't magically format unformatted code) and then press the code button, and your code will have tags.

Another way to do this is to manually place the tags into your code by placing the tag [code] above your pasted code and the tag [/code] below your pasted code like so:

[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]

Good luck!

can you help me how to use this code.. i know how to use it but when i press the rock button the image did not display..

  
		btnRock.addActionListener(new ActionListener(){
					public void actionPerformed(ActionEvent e){
						itemUsers.setText(""); //how can i set here so when i press the button image will display in label
						itemUsers.setText(r);
						user = r;
								}
							}
				);

I would have 3 ImageIcons, one for a rock (let's call it rockIcon), one for a scissors, one for a paper. I would have a JLabel, let's call it imageLabel that is a class variable and thus will be visible from within the action listener. Then within the actionperformed, I'd call imageLabel.setIcon(rockIcon);

So actually you don't even need a CardLayout to solve this problem.

Here's a small program that demonstrates this. For this to work on your system, you'll have to change the image file names and image path to match some on your system:

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JComponent;

public class SwapImages
{
  // these are images present in my classpath.  You'll have to change
  // these constants to test this program on your system
  private static final String IMAGE_PATH = "src/yr2009/m02/c/images/";
  private static final String IMAGE1 = "Bullfight.jpg";
  private static final String IMAGE2 = "Thinking.jpg";
  
  private static final String SHOW_IMAGE_1 = "Show Image 1";
  private static final String SHOW_IMAGE_2 = "Show Image 2";
  private JPanel mainPanel = new JPanel();
  private ImageIcon icon1;
  private ImageIcon icon2;
  private JLabel imageLabel = new JLabel();
  
  public SwapImages()
  {
    try
    {
      // create images
      BufferedImage image1 = ImageIO.read(new File(IMAGE_PATH + IMAGE1));
      BufferedImage image2 = ImageIO.read(new File(IMAGE_PATH + IMAGE2));
      
      // turn them into image icons
      icon1 = new ImageIcon(image1);
      icon2 = new ImageIcon(image2);
      
      // get the largest dimension and set image labe's preferred size
      // to this dimension
      int width = Math.max(image1.getWidth(), image2.getWidth());
      int height = Math.max(image1.getHeight(), image2.getHeight());
      imageLabel.setPreferredSize(new Dimension(width, height));
      
      // create buttons that show images, use constant Strings as button's
      // Strings.  These will be the same as the button's actionCommand
      // Strings that will be tested in the action listener
      JButton showImage1Btn = new JButton(SHOW_IMAGE_1);
      JButton showImage2Btn = new JButton(SHOW_IMAGE_2);
      ButtonListener btnListener = new ButtonListener();
      showImage1Btn.addActionListener(btnListener);
      showImage2Btn.addActionListener(btnListener);
      
      JPanel buttonPanel = new JPanel();
      buttonPanel.add(showImage1Btn);
      buttonPanel.add(showImage2Btn);
      
      mainPanel.setLayout(new BorderLayout());
      mainPanel.add(imageLabel, BorderLayout.CENTER);
      mainPanel.add(buttonPanel, BorderLayout.SOUTH);
    }
    catch (IOException e)
    {
      e.printStackTrace();
    }
  }

  public JComponent getComponent()
  {
    return mainPanel;
  }
  
  private class ButtonListener implements ActionListener
  {
    public void actionPerformed(ActionEvent e)
    {
      String command = e.getActionCommand();
      if (command.equals(SHOW_IMAGE_1))
      {
        imageLabel.setIcon(icon1);
      }
      else if (command.equals(SHOW_IMAGE_2))
      {
        imageLabel.setIcon(icon2);
      }
    }
  }
  private static void createAndShowUI()
  {
    JFrame frame = new JFrame("SwapImages");
    frame.getContentPane().add(new SwapImages().getComponent());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }

  public static void main(String[] args)
  {
    java.awt.EventQueue.invokeLater(new Runnable()
    {
      public void run()
      {
        createAndShowUI();
      }
    });
  }
}
