 1 import javax.swing.*;
 2 public class Test extends JFrame{
 3     public void init(){
 4         //传递参数使得关闭按钮有效
 5         this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
 6         this.setTitle("JFrame");
 7         this.setSize(400,300);
 8         this.setVisible(true);
 9     }
10     
11     public static void main(String[] args){
12         Test jFrame=new Test();
13         jFrame.init();
14     }
