This chapter is the last lecture on design patterns. It will talk about the third design pattern-behavioral pattern, with a total of 11 types: policy pattern, template method pattern, observer pattern, iterative sub-pattern, responsibility chain pattern, command pattern, memo pattern, state pattern, visitor pattern, intermediary pattern and interpreter pattern. I have been writing about design patterns for a long time. At last it's halfway through, Writing a blog post is a very time-consuming thing, Because I have to be responsible for the readers, Whether it's graphs, codes, or representations, Everyone hopes to write it as clearly as possible so that readers can understand it. I think both I and the readers hope to see high-quality blog posts come out. Starting from myself, I will stick to it and update it continuously. The continuous motivation comes from the continuous support of readers and friends. I will do my best to write every article well! I hope everyone can give opinions and suggestions continuously and jointly create a perfect blog post!
A common view is that hearing is the last feeling to disappear, so chatting may be the last comfort for dying relatives.

好气魄。
It is found that many beginners of design patterns have some characteristics, that is, after learning a certain design pattern, they seem to understand it, but they do not know how to use these so-called elite experiences and suffer from not knowing how to start. When I first learned design patterns, I had similar experiences. I shared my experiences, hoping to be helpful to beginners.

The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu
