If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.
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:
"It 's a flying bee, Wings are particularly numerous, He was covered in yellow and black, It is the way yellow and black are arranged in such a way. One by one is as big as a slap with an open hand. As soon as it flies, it is a large area. There is a poisonous needle behind the belly, It stings people, One can kill you, My comrades around me, Because there are no fewer than five sacrifices, I remember when the battle was coming to an end, I helped a comrade-in-arms who was stung to squeeze poison out, To squeeze, The wound, which was almost the size of a grain of rice, gushed out a pale yellow 'water', Sprayed directly on my neck, At that time, I felt that my neck was burning, then I felt pain first, then numbness. At the most numbness, my whole head lost consciousness. My neck drooped down and my comrades washed the spilled place several times with river water. It took me a long time to recover. I thought that it was the same when I sprayed it on my body. If I stung it directly into my body, I would basically not live. " Zhang Xiaobo pointed to his neck as he said.
Note: For example, if you download a famous name (US version), you must download a famous name (world). The world is the main rom of the game, that is, the English letters under the "main body". Any game is, you must have a main rom, and other cloned versions can only be played.
