谁能给我一段用Java 加载和显示BMP(位图)的代码?

import javax.imageio.ImageIO;
import java.util.Arrays;
/**
*列出Java支持的图片格式
*需要JRE1.5或以后
*/
public class SupportedImage{
public static void main(String[] args){
System.out.println(\"支持写的图片格式:\" +Arrays.toString(ImageIO.getWriterFormatNames()));
System.out.println(\"支持读的图片格式:\" +Arrays.toString(ImageIO.getReaderFormatNames()));
}
}

import javax.imageio.ImageIO;
import java.awt.*;
import java.io.*;
import java.util.Arrays;
import javax.swing.*;
/**
*加载现示BMP图象,需要JDK1.5或以上
*@author Eatsun
*/
public class ShowBmp extends JFrame{
public ShowBmp(String bmpFile){
super(\"ShowBmp\");
Image image =null;
try{
image=ImageIO.read(new File(bmpFile));
}catch(IOException ex){
}
JLabel label =new JLabel(new ImageIcon(image));
add(label);
setDefaultCloseOperation(EXIT_ON_CLOSE);
pack();
}
public static void main(String[] args){
final String fileName =\"test.bmp\"; //把这个该成你自己的bmp图片名

SwingUtilities.invokeLater(new Runnable(){
public void run(){
new ShowBmp(fileName).setVisible(true);
}
});
}
}
