我想做一个程序基于JFrame,用JLabel显示两张图片,图片隔两秒种换一次,请问如何用线程来做?谢谢
我下面的程序没做完,请大家帮帮忙:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.applet.*;
import java.net.URL;
import javax.swing.event.*;
class Demo extends JFrame
{
Demo()
{
MyPanel mp=new MyPanel();
new Thread(mp).start();

this.getContentPane().add(mp);
setSize(400,300);
setVisible(true);
}
public static void main(String[] args)
{
Demo dm=new Demo();

}
}

class MyPanel extends JPanel implements Runnable
{
//JLabel jlbl;
public void run()
{
URL u;
try
{
u=Class.forName("Demo").getResource("donghua/1.gif");
// Image img=this.getToolkit().getImage;

// Thread.sleep(2000);
// u=Class.forName("Demo").getResource("donghua/2.gif");
}
catch (Exception ex)
{
ex.printStackTrace();
}

}
}
