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!3.
