I started to do this today. Because it was modified based on a previous small project and not from scratch, I cannot share all the code. Here I will record my daily ideas, I hope to give some suggestions to those who need them. The idea is actually the content of the previous blog.

1 Package: Package is to ensure that the software has a good modular basis, is to achieve the software components of the "high cohesion", "low coupling." In the programming of Face objects, the object is the most basic unit of encapsulation.2 Inheritance: When defining and implementing a class, you can do it on the basis of an existing class, the content defined by the already existing class as its own content, and can add a number of new content, or
