action.java

这个是我们学JAVA时的一个关于APPLET动画的代码实例

import java.awt.*;
import java.applet.*;
public class action extends Applet implements Runnable
{
	Image img;
	Thread runner;
	int xpos=0;
	int ypos=50;
	public void init()
	{
		img=getImage(getCodeBase(),"1.jpg");
	}
	public void start()
	{
		if(runner==null)
		{
			runner=new Thread(this);
		    runner.start();
		}		
	} 
	public void stop()
	{
		if(runner!=null)
		{
			runner.stop();
			runner=null;
		}
	}
	public void run()
	{
		while(true)
		{
			for(xpos=0;xpos<getSize().width;xpos+=5)
			{
				repaint();
				try
				{
					runner.sleep(100);
				}
				catch(InterruptedException e)
				{
				}
			}
		}
	} 
	public void paint(Graphics g)
	{
		g.drawImage(img,xpos+10,ypos,this);
	}
}
