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.

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!
