Answer 1

// 这是一个嵌入到网页中动态显示50是张图片的java小应用程序，希望你对有帮助！
import java.awt.*;

import java.applet.*;
public class Picture extends Applet
{
Image[] theImages;
int nNum = 50;
int nNow = 0;

public void init()
{
theImages = new Image[nNum];
for(int i = 0; i < nNum ; i++)//将图片装入数组
theImages[i] = getImage(getDocumentBase(), "pic" + Integer.toString(i) + ".jpg");
}
public void start()
{
nNow = 0;
}
public void paint(Graphics g)
{
g.drawImage(theImages[nNow],500,500,this);
nNow++;
if(nNow>=nNum)
nNow = 0;
try
{
Thread.sleep(50);
}
catch(Exception e){showStatus(e.toString());}
repaint();
}
public void main()
{
Graphics g;
g=this.getGraphics ();
init();
start();
paint(g);

}
}
