The reason why the logic for creating an object is put into a separate class is that it can be used by multiple clients. And separates the creation and use of objects. However, this design also has many defects. First of all, SimpleFactory is a specific class, so we must program for the implementation, making the system lose its flexibility in this respect. Second, if we add new products, we have to modify the code in SimpleFactory, which violates the opening and closing principle. The above model is also called simple factory. He does not appear in GOF mode, it is more like a programming habit.

The fundamental reason for using design patterns is to adapt to changes, improve code reuse rate, and make software more maintainable and scalable. In addition, the following principles should be followed when designing: single responsibility principle, open and closed principle, Richter substitution principle, dependency inversion principle, interface isolation principle, composite reuse principle and Dimit principle. Each design principle is described below.
刘邦走了，杜殇和柳成也走了。
What we understand is that if a single schema is instantiated, it will only be instantiated once. To implement a single schema, we simply use a variable to identify whether the class is instantiated. If it is not instantiated, then we can instantiate it once. Otherwise, we will directly return the instantiated object.
