/*
* 一、显示图片(图像)
* 1. JLabel: 构造方法 JLabel(Icon image)
* 2. Icon接口: 有一个实现类ImageIcon，它的构造方法是ImageIcon(String filename)

二、设置鼠标
* 3. Window类中的一个方法: public void setCursor(Cursor cursor)
*
* 4.java.awt.Toolkit抽象类中的方法
1)创建自定义光标: public Cursor createCustomCursor(Image cursor, Point hotSpot, String name)
2)创建Image对象: public abstract Image createImage(String filename)
3)创建一个Toolkit对象: public static Toolkit getDefaultToolkit()
5. Image是表示图形图像的所有类的超类

三、分层显示
1. 通过JFrame中的方法" JLayeredPane getLayeredPane() ",获得一个分层面板
2. 在分层面板中添加对象即分层显示: add(Component comp, int index)---把组件comp加在分层面板的index位置，如果index值越小放在越低层
3. 分层显示时需把内容窗格设成透明(用的是JComponent中的方法)：public void setOpaque(false)
