Policy patterns usually wrap a series of algorithms into a series of policy classes. To encapsulate the policy pattern in one sentence is to "encapsulate each algorithm into a different policy class so that they can be interchanged". The following is the structure diagram of the policy mode:1. Creator: FactoryPizzaStore as defined above. It is an abstract class, which defines the method of creating objects. This method is an abstract method, and the specific process of creating objects is implemented by its subclasses. This abstract class usually relies on an abstract Product (another role in the factory method pattern) class. These abstract products are made by subclasses, and the creators do not care what kind of products are made.实则虚之，越是不可能的地方也许是可能性最大的，因此必须要加以防备。At that time, The helmets worn by our army are GK80 bulletproof helmets. After understanding, I am sure that Zhang Xiaobo is wearing this model. The material used to make it is 232 bulletproof steel, which has excellent performance and has good protective effect on various high-speed flying hard objects such as fragments and rubble lifted by explosion. However, because it is a pure metal helmet, it does have the disadvantage of being sultry when fighting in hot conditions.何霆板着脸道：你忙你的，本将军忙本将军的。
