In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.
From the training of professional weightlifters, the belt is usually used only when the leg strength is heavy and the squat is deep. Most players who use belts in professional matches wear them only when they have injuries. If you don't know this, you can naturally count the results. But this "possible explanation" is too superficial. In this way, can I say that wearing knee pads will cause knee injuries in NBA matches? Or do you think frequent visits to dental hospitals will lead to unhealthy teeth?

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:

Memory, which can be divided into two types: one is called random, which is responsible for temporarily storing data waiting for CPU processing, and the data will be lost after power failure. It has no memory function. If the CPU is compared to the carriage of a train, RAM is the platform, and the people who go up and down the train are the data waiting to be processed and can only stay on the platform temporarily. The other is called read-only device, which can only read but not write, and its contents will not be lost after power failure. We will not introduce all the other equipment in the host computer here. In short, they all perform their respective duties to make the computer run normally, thus making the computer a good helper in our work and life.
