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.

There were amateur lifters who failed because they could not get the order to "start" during the competition. After understanding, the referee believed that his heel was unstable and floated upward. Later, I tried weightlifting shoes with relatively high heels. Although I felt smoother after squatting, at the beginning of the movement, weightlifting shoes could not fundamentally solve the problem of deficiency, nor did I feel that shoes had any improvement on my performance. Therefore, it is difficult to say how important weightlifting shoes can play in the strength lifting with relatively wide standing distance and relatively large weight, and there is no need to blindly believe in weightlifting shoes.
