Skin patterns are designed to resolve dependencies between classes and class homes, Like spring, the relationship between classes can be configured into the configuration file, while the appearance mode is to put their relationship in a Facade class, which reduces the coupling degree between classes. There is no interface involved in this mode. Look at the following class diagram: (Let's take the startup process of a computer as an example)
但是点开一看，他们发现并不是。
9-7 Administrators: Administrators are special users. Write a class named Admin that inherits the User class you wrote to complete Exercise 9-3 or Exercise 9-5.

Facing these problems, the best solution is to use visitor mode, which is suitable for systems with relatively stable data structure, decoupling data structure and algorithm,
