Design Mode: Object-oriented

Design Mode: Object-oriented

The so-called design principles or design patterns are nothing more than those created on the premise of object-oriented. The premise of object-oriented is abstraction. The three features of object-oriented are encapsulation, inheritance, and polymorphism. To understand the design patterns in essence, let's analyze the relationships between these concepts. See:

The premise of Object-oriented thinking is abstraction, which abstracts some common objects or classes from the real world and encapsulates them into classes or abstract classes or interfaces. These classes or interfaces are used to increase code reusability. Since they are used for reuse, subclass inheritance is required. In order to satisfy the Personalized Requirements of sub-classes during the inheritance process, polymorphism naturally emerges. In order to better reflect the object-oriented thinking, we have a series of design principles, and the design model is only a concrete manifestation of the design principles.

When we have been working on a design model for so long, we have to fundamentally understand what a knowledge is? Why? If not, what will happen ?" These essential things can be more vital in essence.
