The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.

Encapsulating the code that creates the object in one place can also achieve the purpose of reuse and is more convenient for later maintenance. This also means that when the customer instantiates the object, he will only rely on the interface and not on the specific implementation. Help us to better achieve interface programming rather than implementation, making the code more flexible to cope with future extensions.
