1、Java 应用程序窗口关闭的六种方法Java 应用程序窗口关闭的六种方法：1.使用 JFrame 的 enableEvents 和 processWindowEvent/ /Frame1.javaimport java.awt.*;import java.awt.event.*;import javax.swing.*;public class Frame1 extends JFrame public Frame1() enableEvents(AWTEvent.WINDOW_EVENT_MASK);this.setSize(new Dimension(400, 300);this.setTi
2、tle(“Frame1“);protected void processWindowEvent(WindowEvent e) super.processWindowEvent(e);if (e.getID() = WindowEvent.WINDOW_CLOSING) System.exit(0);2.直接实现 WindowListener 接口/Frame1.javaimport java.awt.*;import java.awt.event.*;public class Frame1 extends Frame implements WindowListener public Frame
3、1() this.setSize(new Dimension(400, 300);this.setTitle(“Frame1“);this.addWindowListener(this);public void windowClosing(WindowEvent windowEvent) System.exit(0);public void windowOpened(WindowEvent windowEvent) public void windowClosed(WindowEvent windowEvent) public void windowIconified(WindowEvent
4、windowEvent) public void windowDeiconified(WindowEvent windowEvent) public void windowActivated(WindowEvent windowEvent) public void windowDeactivated(WindowEvent windowEvent) 3.直接继承窗体适配器 WindowAdapter/Frame1.javaimport java.awt.*;import java.awt.event.*;public class Frame1 extends WindowAdapter pub
5、lic Frame1() Frame f=new Frame();f.setSize(new Dimension(400, 300);f.setTitle(“Frame1“);f.addWindowListener(this);f.setVisible(true);public static void main(String s)new Frame1();public void windowClosing(WindowEvent windowEvent) System.exit(0);4.间接继承窗体适配器 WindowAdapter/Frame1.javaimport java.awt.*;
6、import java.awt.event.*;public class Frame1 extends Frame public Frame1() this.setSize(new Dimension(400, 300);this.setTitle(“Frame1“);this.addWindowListener(new winAdapter();this.setVisible(true);public static void main(String s)new Frame1();class winAdapter extends WindowAdapterpublic void windowC
7、losing(WindowEvent windowEvent) System.exit(0);5.间接实现 WindowListener 接口/Frame1.javaimport java.awt.*;import java.awt.event.*;public class Frame1 extends Frame public Frame1() this.setSize(new Dimension(400, 300);this.setTitle(“Frame1“);this.addWindowListener(new winEventHandle();this.setVisible(true
8、);public static void main(String s)new Frame1();class winEventHandle implements WindowListener public void windowClosing(WindowEvent windowEvent) System.exit(0);public void windowOpened(WindowEvent windowEvent) public void windowClosed(WindowEvent windowEvent) public void windowIconified(WindowEvent
9、 windowEvent) public void windowDeiconified(WindowEvent windowEvent) public void windowActivated(WindowEvent windowEvent) public void windowDeactivated(WindowEvent windowEvent) 6.使用 Inner Class/Frame1.javaimport java.awt.*;import java.awt.event.*;public class Frame1public Frame1()Frame f=new Frame()
10、;f.addWindowListener(new WindowAdapter()public void windowClosing(WindowEvent e)System.exit(0););f.setSize(new Dimension(400, 300);f.setVisible(true);public static void main(String s)new Frame1();Jframe 的关闭方法：setDefaultCloseOperation(EXIT_ON_CLOSE);frame 的关闭方法如下：this.addWindowListener(new java.awt.event.WindowAdapter() public void windowClosing(java.awt.event.WindowEvent e) System.exit(0););
