applet1.java

用java编写的一些初级代码

import java.awt.*;
import java.applet.*;
import java.net.*;

public class Applet1 extends Applet implements Runnable
{
    int index=0;
    Image [] imgs=new Image[10];
    public  void init()
    {
	try{
	    for(int i=0;i<10;i++)
	    {
		imgs[i]=getImage(new URL(getCodeBase(),"T"+(i+1)+".gif"));
	    }
	new Thread (this).start();}
	catch(Exception e){}
    }
    public  void paint(Graphics g)
    {
	g.drawImage(imgs[index],0,0,this);
	g.setFont(new Font("",Font.BOLD,30));
	index=(index+1)%10;
	g.drawString(""+index,0,50);
    }
    public void run()
    {
	while(true)
	{
	    repaint();
	    try
	    {
		Thread.sleep(123);
	    }
	    catch(Exception e){}
	}
    }
}
