1.整体的结构图：

2.编写GameFrame02.java代码：

package cn.bjsxt.test;import java.awt.Frame;import java.awt.Graphics;import java.awt.Image;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;public class GameFrame02 extends Frame {Image image = GameUtil.getImage("images/sun.jpg");public void launchFrame() {setSize(500, 500);setLocation(100, 100);setVisible(true);new PaintThread().start();addWindowListener(new WindowAdapter() {// 单击右键选择“source”中的“override/implement// methods”，frame里面勾选“windowClosed”点击“OK”@Overridepublic void windowClosing(WindowEvent e) {System.exit(0);}});}private double x = 100, y = 100;private boolean left;private boolean up;// 单击右键选择“source”中的“override/implement// methods”，window里面勾选“paint(graphic)”点击“OK”@Overridepublic void paint(Graphics g) {g.drawImage(image, (int) x, (int) y, null);if (left) {x -= 3;} else {x += 3;}if (x > 500 - 130) {left = true;}if (x < 0) {left = false;}if (up) {y -= 5;} else {y += 5;}if (y > 500 - 130) {up = true;}if (y < 30) {up = false;}}class PaintThread extends Thread {public void run() {while (true) {repaint();try {Thread.sleep(40);} catch (InterruptedException e) {e.printStackTrace();}}}}public static void main(String[] args) {GameFrame02 gf = new GameFrame02();gf.launchFrame();}}

3.编写GameUtil.java的代码：

package cn.bjsxt.test;import java.awt.Image;import java.awt.image.BufferedImage;import java.io.IOException;import java.net.URL;import javax.imageio.ImageIO;public class GameUtil {private GameUtil() {}public static Image getImage(String path) {URL u = GameUtil.class.getClassLoader().getResource(path);BufferedImage image = null;try {image = ImageIO.read(u);} catch (IOException e) {e.printStackTrace();}return image;}}

4.运行之后的结果：
