[Java]在窗口界面上画出硬盘中图片文件

　　利用类javax.swing.JPanel来在窗口界面上画图。图片文件通过javax.imageio.ImageIO类来获取。

 import java.awt.Graphics;
 import java.awt.image.BufferedImage;
 import java.io.File;
 import java.io.IOException;

 import javax.imageio.ImageIO;
 import javax.swing.JFrame;
 import javax.swing.JPanel;

 import com.Sunday.TankWar.configure.TankWarConfigure;

 public class ImageFrame {

     private BufferedImage image;
     private String imageName = "home.jpg";

     public ImageFrame() throws IOException {
         image = ImageIO.read(new File(TankWarConfigure.imagePath + imageName));
     }

     @SuppressWarnings("serial")
     class Background extends JPanel {
         public void paint(Graphics g) {
             g.drawImage(image, 0, 0, null);
             g.drawImage(image, 100, 100, null);
         }
     }

     public static void main(String[] args) throws Exception {
         ImageFrame image = new ImageFrame();
         JPanel jpanel = image.new Background();
         JFrame frame = new JFrame("图片测试");
         frame.add(jpanel);
         frame.setBounds(0, 0, 200, 220);
         frame.setVisible(true);
     }

 }
