One, strategy (strategy) modeThe intent of the policy pattern is to encapsulate each algorithm in a separate class with a common interface for a set of algorithms, so that they can be replaced with each other. The policy pattern allows the algorithm to change without affecting the client.Suppose you are designing a shopping cart (shopping Cat) system that sells e-commerce sites for all kinds of books.
