[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);
    }

}
