In the system, the client often needs to interact with multiple subsystems, which causes the client to change with the change of subsystems. At this time, the appearance mode can be used to decouple the client from each subsystem. Appearance mode refers to providing a consistent facade for a group of interfaces in the subsystem. It provides a high-level interface that makes the subsystem easier to use. For example, the customer specialist of Telecom can let the customer specialist complete the services such as charging telephone charges and modifying packages without interacting with various subsystems by himself. The specific class structure diagram is as follows:

For interface programming, a lot of changes that may occur in the system in the future can be isolated. Why? If the code is written for an interface, he can implement the interface with any new class through polymorphism. However, when the code uses a large number of specific classes, once new specific classes are added, the code must be changed. Violating the opening and closing principle.
