请求达人 分析下这个程序

调试时报错
  BounceApplet.java  使用或覆盖了已过时的API
 了解详细信息,请使用 -Xlint:deprecation 重新编
请问如何解决这问题
谢谢
源代码如下

  1.   

    我还以为是什么呢........
    show
    @Deprecated
    public void show(boolean b)已过时。 从 JDK version 1.1 开始，由 setVisible(boolean) 取代。 这么改
    public class BounceApplet extends Applet
    {   public BounceApplet ()
       {  BounceExpress bounce = new BounceExpress();
          bounce.setSize(300,200);
          bounce.setVisible(true);}
    }
