为什么运行没有界面,好像窗口直接就关闭了

setDefaultCloseOperation(this.EXIT_ON_CLOSE);
就可以在窗口关闭的时候关掉进程了吧
++main 方法里 创建一个MyFrame 对象 MyFrame m=new MyFrame();
import java.awt.*;
import java.awt.event.*;public class TestWindowClose {
public static void main (String[] args) {
String s = null;
MyFrame myFrame=new MyFrame(s);
}
}class MyFrame extends Frame{
MyFrame(String s){
super(s);
setLayout(null);
setBounds(300,300,400,300);
this.setBackground(new Color(204,204,255));
setVisible(true);
this.addWindowListener(
new WindowAdapter(){
public void windowClosing(WindowEvent e){
setVisible(false);
System.exit(-1);
}
}
);
}
}
