由于想一次上传成功 所以将二个教程打包成了一个 这些例子几乎包含了所有java的框架集合

public class mediatracker extends Applet 
{
    Image image;

    public void init() 
    {
        MediaTracker tracker = new MediaTracker(this);
        image = getImage(getDocumentBase(), "image.jpg");
        tracker.addImage(image, 0);
        try {
            tracker.waitForAll();
        }
        catch (InterruptedException ex) { }
  }

    public void paint(Graphics g) 
    {
        g.drawImage(image, 10, 10, this);
    }
