4. Using Java code as an example to explain the simple factory pattern in the design pattern

Introduction: Simply put, the factory pattern returns a type of object according to requirements. The meaning of using the factory pattern is that if If the instantiation and code dependence of the object are too large, it will be inconvenient to expand and maintain. The purpose of using the factory is to decouple the instantiation of the object from the main program code. Let’s take a closer look:

5. Commonly used design patterns in java

Introduction: Design Patterns; A programmer’s understanding of design patterns: “I don’t understand” why a very simple thing should be made so complicated. Later, as my experience in software development increased, I began to understand that the "complexity" I saw was exactly the essence of design patterns. What I understood as "simplicity" was the pattern of using a key to open a lock, and the purpose was just to focus on To solve the current problem, the "complexity" of the design pattern lies in that it is to construct a "master key" with the purpose of proposing a solution for unlocking all locks. Before I really understood the design pattern, I had been writing "simple" code. This "simple" is not the simplicity of the function, but the simplicity of the design. Simple design means lack of flexibility, the code is very rigid, only useful in this project, get other
