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.

State mode refers to allowing an object to change its behavior when its internal state changes. The object seems to have modified its class. Divide this sentence into two parts by commas. The first part means to encapsulate the state into a separate class and delegate the request to the current state object. When the internal state of the object changes, different behavior changes will be brought about. The second part is from the customer's point of view, the object used has completely different behaviors in different states. The object seems to be instantiated from different classes, but in fact this is the effect of using delegates.
