Java应用程序窗口关闭的方法

1.使用JFrame的enableEvents和processWindowEvent

 

import java.awt.*;import java.awt.event.*;import javax.swing.*;public class MainFrame extends JFrame {   public MainFrame() {    enableEvents(AWTEvent.WINDOW_EVENT_MASK);    this.setSize(new Dimension(465, 219));    this.setTitle("JLabelDemo1");      }   protected void processWindowEvent(WindowEvent e) {    super.processWindowEvent(e);    if (e.getID() == WindowEvent.WINDOW_CLOSING) {      System.exit(0);    }  }}

 2.JFrame的关闭方法：

　  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
