用JAVA在界面中实现幻灯片播放，求代码

要让照片随机播放,需要把照片名改成比如photo1.jpg,photo2.jpg,photo3.jpg...的有序号顺序排列的文件名,

然后把改名后的照片文件放到你的项目名的目录下,比如你的项目名叫"slideshow",你就把照片文件放到slideshow文件夹下.

最后把下面的Java程序拷贝到你的项目中,把有DD类名的地方改成你的类名,就行了.

完整的让一些照片在JFrame窗体里自动随机播放的幻灯片程序如下

(我用的图片文件是photo1.jpg,photo2.jpg,photo3.jpg,注意事项在注释中注明

import java.awt.Graphics;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

public class DD extends JFrame implements Runnable{

ImageIcon ii=new ImageIcon("photo1.jpg");//这里换成你的图片文件名,放在你的项目名的文件夹中

DD(){

super("Slide");

setSize(400, 400);

setLocationRelativeTo(null);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setVisible(true);

}

public void paint(Graphics g){

super.paint(g);

g.drawImage(ii.getImage(),0,0,400,400,null);

}

@Override

public void run() {

while(true){

try {

Thread.sleep(500);//这里是幻灯片播放间隔的时间,这里为500毫秒=0.5秒

} catch (InterruptedException e) {

e.printStackTrace();

}

int i=(int)(Math.random()*3)+1;//这里是产生从1-3的随机数,如果你有6个图片文件,把3改成6就是从1-6的随机数了.

ii=new ImageIcon("photo"+i+".jpg");//这里调用你的图片文件,如果你有6个图片文件,改成从1-6的文件名方便调用

this.repaint();

}

}

public static void main(String[] args) {

DD d=new DD();

Thread t=new Thread(d);

t.start();

}

}

把你的图片地址 在jsp加载的时候 循环上去 就可以了 如果可以 记得给分哦

请给我的JAVA程序添加一个自动播放图片功能

//其余的类在qq上给你..
