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.Every time I go to the United States, I will struggle with which clothes and shoes to bring, especially shoes, which take up a lot of space.
