Am I missing the point

Question

Hi
Why in the following bit of code does the window not close when I close the frame, I understand why it closes and end's when I take the "open" option on the menu.
I want to know why to get a better undersstanding as opposed to the solution.
import java.awt.event.* ;
import javax.swing.* ;
public class AppMenu1 {
     public static void main(String[] args) {
          JMenuBar menuBar = new JMenuBar();
          JMenu menu1 = new JMenu("File");
          menuBar.add(menu1);
          JMenu menu2 = new JMenu("Edit");
          menuBar.add(menu2);
          JMenuItem item1 = new JMenuItem("Open");
          menu1.add(item1);
          item1.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    System.exit(0);
          JMenuItem item2 = new JMenuItem("Save");
          menu1.add(item2);
          JMenuItem item21 = new JMenuItem("Edit");
          menu2.add(item21);
          JMenuItem item22 = new JMenuItem("Find");
          menu2.add(item22);
          JFrame frame = new JFrame();
          frame.setJMenuBar(menuBar);
          frame.setVisible(true);
          frame.addWindowListener(new WindowAdapter() {
               public void WindowClosing() {
                    System.exit(0);
}thanks in adavnce

Gurmej,
Your problem is here :
public void WindowClosing() {The Actual signatue is:
public void windowClosing(WindowEvent e)
Java is case sensitive and also you left out the parameter
