Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data.

First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.Proxy mode refers to providing a proxy to an object and controlling access to the original object by the proxy object.
