First of all, A and B will play a match.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在杨长帆眼里，父亲现在就是那个想法特别周全的人，在礼数和分寸上，在老油条的火候程度上，他一定是高明于自己的，这时的社会有这时的规矩，自己该请教请教。Enter the inventory selection interface as shown above, and pay attention to the contents to be checked.
