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.java　　importjava.awt.*;　　importjava.awt.event.*;　　importjavax.swing.*;　　publicclassFrame1extendsJFrame{　　publicFrame1(){　　enableEvents(AWTEvent.WINDOW_EVENT_MASK);　　this

2、.setSize(newDimension(400,300));　　this.setTitle("Frame1");　　}　　protectedvoidprocessWindowEvent(WindowEvente){　　super.processWindowEvent(e);　　if(e.getID()==WindowEvent.WINDOW_CLOSING){　　System.exit(0);　　}　　}　　}　　2.直接实现WindowListener接口　　//Frame1.java　import

3、java.awt.*;　　importjava.awt.event.*;　　publicclassFrame1extendsFrameimplementsWindowListener{　　publicFrame1(){　　this.setSize(newDimension(400,300));　　this.setTitle("Frame1");　　this.addWindowListener(this);　　}　　publicvoidwindowClosing(WindowEventwindowEvent

4、){　　System.exit(0);　　}　　publicvoidwindowOpened(WindowEventwindowEvent){}　　publicvoidwindowClosed(WindowEventwindowEvent){}　　publicvoidwindowIconified(WindowEventwindowEvent){}　　publicvoidwindowDeiconified(WindowEventwindowEvent){}　　publicvoidwindowActivat

5、ed(WindowEventwindowEvent){}　　publicvoidwindowDeactivated(WindowEventwindowEvent){}　　}　　3.直接继承窗体适配器WindowAdapter　//Frame1.java　　importjava.awt.*;　　importjava.awt.event.*;　　publicclassFrame1extendsWindowAdapter{　　publicFrame1(){　　Framef=newFrame();　　f.setS

6、ize(newDimension(400,300));　　f.setTitle("Frame1");　　f.addWindowListener(this);　　f.setVisible(true);　　}　　publicstaticvoidmain(String[]s){　　newFrame1();　　}　　publicvoidwindowClosing(WindowEventwindowEvent){　　System.exit(0);　　}　　}　　4.间接继承窗体适配器WindowAdapter　//

7、Frame1.java　　importjava.awt.*;　　importjava.awt.event.*;　　publicclassFrame1extendsFrame{　　publicFrame1(){　　this.setSize(newDimension(400,300));　　this.setTitle("Frame1");　　this.addWindowListener(newwinAdapter());　　this.setVisible(true);　　}　　publicstaticvoid

8、main(String[]s){　　newFrame1();　　}　　}　　classwinAdapterextendsWindowAdapter{　　publicvoidwindowClosing(WindowEventwindowEvent){　　System.exit(0);　　}　　}　　5.间接实现WindowListener接口　//Frame1.java　　importjava.awt.*;　　importjav
