public class HelloJava{
  public static void main (String[] args){
  Image image = null;
   try {
       // Read from a file
       File sourceimage = new File("source.gif");  //source.gif图片要与HelloJava.java同在一目录下
       image = ImageIO.read(sourceimage);
  
       // Read from an input stream
       InputStream is = new BufferedInputStream(
          new FileInputStream("mid.jpg"));  //mid.jpg图片要与HelloJava.java同在一目录下
       image = ImageIO.read(is);
  
       // Read from a URL
       URL url = new URL("http://www.javaworld.com/images/012407-tipsbox.jpg");
       image = ImageIO.read(url);
   } catch (IOException e) {
   }
