/*
* ※图片显示：
* 1. JLabel类: 构造方法 JLabel(Icon image)
2. Icon接口：有一个实现类为ImageIcon，它的构造方法：ImageIcon(String filename)
※自定义鼠标--设置光标
3. java.awt.Toolkit工具类:
函数一：public Cursor createCustomCursor(Image cursor, Point hotSpot, String name)：可以创建一个自定义的光标(鼠标)
函数二：public abstract Image createImage(String filename)创建并返回一个Image对象
函数三：public static Toolkit getDefaultToolkit()获取默认工具包
4.Image类：是表示图形图像的所有类的超类
5.给窗口设置光标：void java.awt.Window.setCursor(Cursor cursor)
※图片和组件的叠加显示
6.JFrame类中的一个函数
public JLayeredPane getLayeredPane()返回此窗体的 layeredPane对象
通过JLayeredPane对象添加的组件可以分层叠加显示
