java小游戏第二弹 打地鼠

/*打地鼠

* 本版只是单纯的图形接界面运用

* 图片编程要用到的API----应用程序接口

* 1, JLabel: JLabel(Icon image)

* 2, Icon接口---可以封装固定大小的小图片，通常用于装饰界面组件

* 3, ImageIcon----是Icon接口的实现类，当然可以当作Icon来用。

* ImageIcon(String filename)---说明该对象可以通过文件名来生成

4, Toolkit---抽象类，我们不能new对象，因此通过它的工厂方法获取---getDefaultTookit

public abstract Image createImage(String filename)---可以通过文件名创建一个图片

public Cursor createCustomCursor(Image cursor,Point hotSpot,String name)---创建自定义光标

5,Window类(JFrame的父类)

public void setCursor(Cursor cursor)-----设置光标

6, JFrame类中的方法

public JLayeredPane getLayeredPane() ----返回窗体的 layeredPane对象----窗体分层显示
