*※ picture shows:
* 1. JLabel class: Construction method JLabel (Icon image)
2. Icon interface: There is an implementation class for ImageIcon, which constructs the method: ImageIcon (String filename)

※ Custom Mouse--set cursor
3. Java.awt.Toolkit Tool Class:
Function One: Public cursor createcustomcursor (Image cursor, point hotSpot, String name): Can create a custom cursor (mouse)
Function two: Public abstract image CreateImage (String filename) creates and returns an Image object
Function three: public static Toolkit Getdefaulttoolkit () Get the default toolkit
Class 4.Image: A superclass that represents all classes of a graphics image
5. Set the cursor to the window: void java.awt.Window.setCursor (cursor cursor)

* Overlay display of pictures and components
A function in the 6.JFrame class
Public JLayeredPane Getlayeredpane () returns the Layeredpane object for this form
Components added through the JLayeredPane object can be layered overlay display
