java怎么在JFrame中显示动态图片？

比如我有一个gif的动态图片 我想在JFrame中拿他做背景 可是我添加进去运行的时候他不会动…… 问度娘后貌似说是只能一帧一帧显示…… 求高手给一段代码看看！！

import java.awt.Graphics;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

import javax.swing.JPanel;

public class ImageApp extends JFrame {

public ImageApp() {

setDefaultCloseOperation(EXIT_ON_CLOSE);

setLocationRelativeTo(null);

setSize(400, 300);

setResizable(false);

getContentPane().setLayout(null);

JPanel panel = new ImagePanel();

panel.setBounds(0, 0, 400, 300);

getContentPane().add(panel);

setVisible(true);

}

public static void main(String[] args) {

new ImageApp();

}

class ImagePanel extends JPanel {

public void paint(Graphics g) {

super.paint(g);

// ImageIcon icon = new ImageIcon("D:\\1.jpg");

ImageIcon icon = new ImageIcon("D:\\14405937jqhjsppeninjf9.gif");

g.drawImage(icon.getImage(), 0, 0, 400, 300, this);

}

将gif的动态图片拆成一帧一帧的图片，用Time类及设置背景 的方法改变背景图片
