Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:5.1 The syntax is as follows:"Liu Guiduo was executed in the spring of 2016. While still inside, Once I walked past the room where Liu Guiduo was locked up in handcuffs and shackles. He saw me and raised his hand. At that time, he could only raise his right hand a little. He pointed at me and then withdrew it. He made a shot posture at the head with a smile on his face, just like I saw when he killed Second Officer Wang Yongbo.
