JLabel click event to change picture

Question

Hi All,
I am new to GUI programming and need some help.
I am trying to get a picture of a match to change to a different picture of a match when i click on it.
Below is how I'm currently trying to do it.
import javax.swing.UIManager;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Application2 {
  boolean packFrame = false;
  //Construct the application
  public Application2() {
    Frame2 frame = new Frame2();
    //Validate frames that have preset sizes
    //Pack frames that have useful preferred size info, e.g. from their layout
    if (packFrame) {
      frame.pack();
    else {
      frame.validate();
    //Center the window
    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    Dimension frameSize = frame.getSize();
    if (frameSize.height > screenSize.height) {
      frameSize.height = screenSize.height;
    if (frameSize.width > screenSize.width) {
      frameSize.width = screenSize.width;
    frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
    frame.setVisible(true);
  //Main method
  public static void main(String[] args) {
    try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    catch(Exception e) {
      e.printStackTrace();
    new Application2();
public class Frame2 extends JFrame {
  JPanel contentPane;
  BorderLayout borderLayout1 = new BorderLayout();
  JPanel jPanel1 = new JPanel();
  ImageIcon match = new ImageIcon("match.JPG");
  ImageIcon match2 = new ImageIcon("match2.JPG");
  JLabel jLabel1 = new JLabel(match);
  JLabel jLabel2 = new JLabel(match2);
  //Construct the frame
  public Frame2() {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);
    try {
      jbInit();
    catch(Exception e) {
      e.printStackTrace();
  //Component initialization
  private void jbInit() throws Exception  {
    contentPane = (JPanel) this.getContentPane();
    contentPane.setLayout(borderLayout1);
    this.setSize(new Dimension(400, 300));
    this.setTitle("Frame Title");
    jLabel1.addMouseListener(new Frame2_jLabel1_mouseAdapter(this));
    contentPane.add(jPanel1, BorderLayout.CENTER);
    jPanel1.add(jLabel1, null);
   // jPanel1.add(jLabel2, null);
  //Overridden so we can exit when window is closed
  protected void processWindowEvent(WindowEvent e) {
    super.processWindowEvent(e);
    if (e.getID() == WindowEvent.WINDOW_CLOSING) {
      System.exit(0);
  void jLabel1_mouseClicked(MouseEvent e) {
    // DOESN'T seam to work
    jLabel1 = new JLabel(match2);
   // jPanel1.remove(jLabel1);
   // jPanel1.add(jLabel1);
    jPanel1.repaint();
    repaint();
class Frame2_jLabel1_mouseAdapter extends java.awt.event.MouseAdapter {
  Frame2 adaptee;
  Frame2_jLabel1_mouseAdapter(Frame2 adaptee) {
    this.adaptee = adaptee;
  public void mouseClicked(MouseEvent e) {
    adaptee.jLabel1_mouseClicked(e);
}
