What we understand is that if a single schema is instantiated, it will only be instantiated once. To implement a single schema, we simply use a variable to identify whether the class is instantiated. If it is not instantiated, then we can instantiate it once. Otherwise, we will directly return the instantiated object.

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.

For those who like dogs, I really can't understand the psychology of those who are afraid of dogs. Similarly, I can't understand why some people like dogs so much and compare their hearts with each other. I respect the rights of dog owners. At the same time, I also hope that dog owners will fulfill their obligations as dog owners, take good care of their dogs, hold their dogs, and train them before going out. Just like their children, they should have the minimum education. Your dogs should not bark, pounce on people, defecate anywhere, and then take them out. The dog's behavior reflects the quality of its owner.
