Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different 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.

As soon as the computer algorithm class came up, it recommended the big "Introduction to Algorithms" and the theoretical "Data Mining: Concepts and Technologies". It was not suitable for such beginners. Reading should be ladder-shaped, and one cannot eat into a big fat man in one bite. Because I don't want "Daniel" to mislead people, I give the following suggestions:
