求大家帮我看看哪出错了---在java Application中加载显示图像

[qqjq547]

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class 显示图像 extends JFrame{
Image img1=null;
public static void main(String[] args) {
// TODO Auto-generated method stub
new 显示图像();
}
public 显示图像(){
super("显示图像");
img1=this.getToolkit().getImage("613701870f63d967c75cc322.jpg");
this.setSize(280, 200);
this.setVisible(true);
this.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);}
}
};
public void paint(Graphics g){
g.drawImage(img1,0,20,this);
}
}
