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:
Peter Boyd探长指挥着一支经过多种训练的警探和科学家的警察队伍-悬案小组，使用现代的方法和原来调查时还没有的新科技来专门调查的未破获的老谋杀案。
The third is to use the design pattern flexibly. Even if you don't need any specific pattern, you can design high-quality codes. No sword is better than a sword.
Now we can override the methods in the parent class Interview in the subclass BaiDuInterview; The code is as follows:

In fact, each design pattern is a very important idea, which looks very familiar. In fact, it is because what we have learned is involved. Although sometimes we don't know it, it is actually reflected everywhere in Java's own design, such as AWT, JDBC, collection class, IO pipeline or Web framework, in which design patterns are everywhere. Because of our limited space, it is difficult to talk about every design pattern in great detail, but I will try my best to write down the meaning clearly in the limited space and space so as to make everyone understand better. If there is no accident in this chapter, it should be the last talk of the design pattern. First of all, it should be the figure at the beginning of the previous article:
