就是每隔一定的时间显示一张图片，全部图片文件位于：“工作空间\项目名称\bin\动态图\花好月圆\”文件夹下。文件名类似：1001.jpg,1002.jpg,一直到1016.jpg:

复制代码 代码如下:

/*

 *
 * created on __date__, __time__
 */

package 动态图;

import java.awt.graphics;
import java.awt.image;
import java.awt.image.imageobserver;
import java.io.file;
import java.io.ioexception;

import javax.imageio.imageio;

/**

public class donttai extends javax.swing.jframe implements runnable
{

    /** creates new form donttai */
    public donttai()
    {
        initcomponents();
    }

    //string path = "e:\\workspaces\\myeclipse_9.0\\20120731\\bin\\动态图\\1\\10";
    //java默认文件路径是项目的根目录，所以要手动加上bin及其以下的路径
    string path="bin/动态图/花好月圆/10";
    int idx = 1;

    public void paint(graphics g)
    {
        imageobserver imageobserver = new imageobserver()
        {

            @override
            public boolean imageupdate(image img, int infoflags, int x, int y,
                    int width, int height)
            {
                // todo auto-generated method stub
                return false;
            }
        };
        try
        {
            //g.drawimage(imageio.read(new file(donttai.class.getresource("1.png").tostring())), 20, 20, imageobserver);
            string temp = "";
            if (idx <= 9)
                temp = path + "0" + idx + ".jpg";
            else if (idx >= 10)
            {
                temp = path + idx + ".jpg";
            }
            g.drawimage(imageio.read(new file(temp)), 100, 50, 400, 300,
                    imageobserver);
        }
        catch (ioexception e)
        {

            e.printstacktrace();
        }
    }
