关闭窗体java代码 java关闭窗体的方法 _关闭

java关闭窗体的六种方法前段时间集中精力写了两篇论文很久没写博文了现在继续了
使用JFrame的enableEvents和processWindowEvent
//Frame java
import java awt *;
import java awt event *;
import javax swing *;
public class Frame extends JFrame {
public Frame () {
enableEvents(AWTEvent WINDOW_EVENT_MASK);
this setSize(new Dimension( ));
this setTitle( Frame );
}
protected void processWindowEvent(WindowEvent e) {
super processWindowEvent(e);
if (e getID() == WindowEvent WINDOW_CLOSING) {
System exit( );
}
}
}
直接实现WindowListener接口
//Frame java
import java awt *;
import java awt event *;
public class Frame extends Frame implements WindowListener {
public Frame () {
this setSize(new Dimension( ));
this setTitle( Frame );
this addWindowListener(this);
}
public void windowClosing(WindowEvent windowEvent) {
System exit( );
}
public void windowOpened(WindowEvent windowEvent) {}
public void windowClosed(WindowEvent windowEvent) {}
public void windowIconified(WindowEvent windowEvent) {}
public void windowDeiconified(WindowEvent windowEvent) {}
public void windowActivated(WindowEvent windowEvent) {}
public void windowDeactivated(WindowEvent windowEvent) {}
}
直接继承窗体适配器WindowAdapter
//Frame java
import java awt *;
import java awt event *;
public class Frame extendsWindowAdapter {
public Frame () {
Frame f=new Frame();
f setSize(new Dimension( ));
f setTitle( Frame );
f addWindowListener(this);
f setVisible(true);
}
public static void main(String[] s){
new Frame ();
}
public void windowClosing(WindowEvent windowEvent) {
System exit( );
}
}
间接继承窗体适配器WindowAdapter
//Frame java
import java awt *;
import java awt event *;
public class Frame extendsFrame {
public Frame () {
this setSize(new Dimension( ));
this setTitle( Frame );
this addWindowListener(new winAdapter());
this setVisible(true);
}
public static void main(String[] s){
new Frame ();
}
}
class winAdapter extends WindowAdapter{
public void windowClosing(WindowEvent windowEvent) {
System exit( );
}
}
间接实现WindowListener接口
//Frame java
import java awt *;
import java awt event *;
public class Frame extendsFrame {
public Frame () {
this setSize(new Dimension( ));
this setTitle( Frame );
this addWindowListener(new winEventHandle());
this setVisible(true);
}
public static void main(String[] s){
new Frame ();
}
}
class winEventHandle implements WindowListener {
public void windowClosing(WindowEvent windowEvent) {
System exit( );
}
public void windowOpened(WindowEvent windowEvent) {}
public void windowClosed(WindowEvent windowEvent) {}
public void windowIconified(WindowEvent windowEvent) {}
public void windowDeiconified(WindowEvent windowEvent) {}
public void windowActivated(WindowEvent windowEvent) {}
public void windowDeactivated(WindowEvent windowEvent) {}
}
使用Inner Class
//Frame java
import java awt *;
import java awt event *;
public class Frame {
public Frame (){
Frame f=new Frame();
f addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System exit( );
}
});
f setSize(new Dimension( ));
f setVisible(true);
}
public static void main(String[] s){
