1.整体的结构如下：

2.编写GameFrame.java：

package cn.bjsxt.test;import java.awt.Color;import java.awt.Font;import java.awt.Frame;import java.awt.Graphics;import java.awt.Image;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;public class GameFrame extends Frame {Image image = GameUtil.getImage("images/sun.jpg");public void launchFrame() {setSize(500, 500);setLocation(100, 100);setVisible(true);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);}});}// 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.drawLine(100, 100, 200, 200);g.drawRect(100, 100, 200, 200);g.drawOval(100, 100, 200, 200);Font f = new Font("宋体", Font.BOLD, 30);g.setFont(f);g.drawString("第一次画图", 200, 200);g.fillRect(100, 100, 20, 20);Color c = g.getColor();g.setColor(Color.red);g.fillOval(300, 300, 20, 20);g.setColor(c);g.drawImage(image, 200, 200, null);}public static void main(String[] args) {GameFrame gf = new GameFrame();gf.launchFrame();}}

3.编写GameUtil.java：

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.运行出来的结果如下：
