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:

I have also seen it spray on cars. The fuel burns to extinguish the flame for more than five minutes. When it finally went out, the whole car head was burned by more than half. Although I don't know the specific figure of the temperature, the comrades in the chemical defense class said it was at least 1300-1500 degrees Celsius, so I thought at that time, even the steel plate could melt into the flame of molten iron in a few minutes.

The black corpses of wasps that have been burned apart and fallen and the corpses of wasps that have been smashed by bullets are piled up most. One foot is thick enough to reach the knee. That scene, I
