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.

After all, there are 5 or 6 different materials woven together for real socks, and it is already very good to use 4 kinds of fake socks. I am only a few students, and the team version will not be able to identify them. However, the materials are obviously different when making goods, which cost about 10 yuan. I suggest you be careful.你可能还在奇怪，我为何会出现在这里是吧？那我不妨直接告诉你，来越国就是为了等机会杀你报仇。张槐等人听了一静。When the poor finished eating one sheep, the lamb was not born and the days were difficult again, they could not help eating another. The poor thought, "It's not going to work like this. It's better to sell the sheep and buy chickens. The chickens will lay eggs soon. Once the eggs are sold, the days will improve."可不比这两小子，长了这么大，头一回离开家门。
