public void WindowClosing(WindowEvent e){
    if(e.getID()==WindowEvent.WINDOW_CLOSING)
      System.out.println("关闭按钮已按下!");
System.exit(0);
  }

Answer 1

public void WindowClosing(WindowEvent e){
    if(e.getID()==WindowEvent.WINDOW_CLOSING)
      System.out.println("关闭按钮已按下!");
      dispose();
      System.exit(0);
不知道行不
要是还不行请你把错误提示贴出来

Answer 2

同意guhuan(水云间)的做法，
dispose()关闭窗口；

Answer 3

public void windowClosing(WindowEvent e)
  public void windowIconified(WindowEvent e)
  public void windowActivated(WindowEvent e)
  public void windowStateChanged(WindowEvent e)中 window 首字母w都是小写。
