Answer 1

先设置JFrame：setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
再用JFrame的Closing事件：public void windowClosing(WindowEvent e)
{
if(JOptionPane.showConfirmDialog(this,"Are you sure to exit?","Exit Confirm",JOptionPane.YES_NO_OPTION,JOptionPane.QUESTION_MESSAGE) == JOptionPane.YES_OPTION)
       {
           System.exit(0);
       }
}

guiclose.addWindowListener(new WindowAdapter()
                         {
                 public void windowClosing(WindowEvent e)
                   {
                    if (JOptionPane.showConfirmDialog(null, "你确定退出程序嘛?",
                    "Exit Confirm", JOptionPane.YES_NO_OPTION,
                            JOptionPane.QUESTION_MESSAGE) ==
                        JOptionPane.YES_OPTION) {
                      logger.debug("End Ddebug....");
                      logger.info("leaving the application");
                     // NDC.pop();
                     System.out.println("This is RootLogger...ing ."+logger.getRootLogger());
                      System.exit(0);                    }
                  }
                         });谢谢楼上：这样可以拉！
