Here, the design pattern is introducedPrinciple of object-oriented thought designIn the actual development, we want to understand the object-oriented thinking more deeply, we must be familiar with the design principles of the object-oriented thought that the predecessor

Creation Design Mode
The creation design mode focuses on the object creation mechanism and creates objects in a way suitable for a given situation. Attributes of this category include:
Constructor, Factory, Abstract, Prototype, Singleton, and Builder

Interaction designers often meet this scenario: after a bit of brooding and struggling, the need for PD is quickly completed. Of course, the process is submitted to the visual designer. But in the visual design process, found that some user behavior and operation path, in the demo did not involve, Of course, the visual designer will be back to rework. This is the only way to make sure that the problem is fully designed.
If the interaction designer ca

Factory mode: Define an interface for creating an object, but let subclasses decide which class to instantiate. factory method lets a class defer instantiation to subclass. defines an interface used to create objects so that the subclass decides which class

There is no doubt that the design model is a win-win solution for others and the system. The design model enables code compilation to be truly engineered. The design model is the foundation of software engineering, just like the building blocks.
