Tip: there is a directory above, which can quickly locate the classes you need to see. Today, I made a small modification to the previous code to make the code a little more perfect. As for the user unique identification code UUID, it will be modified to be generated inside the program in the future. The current UUID is still set by the user.

Today, a part of the presentation layer of the user interface is added to this program, and the public class enumeration is added. Below, all the codes of the program I have written are posted: I will gradually finish writing this program, please rest assured! (the functions to be realized can be found in the series of bookstore management system. I have classified the articles of this series for your convenience.) the blogs of this series will not be broken.

Current code layering:

Picture after running the current program:

I post the code from the top of the directory to the bottom: please pay attention! This code order is not the order in which I write code! If you want to refer to my writing, please don't follow the order of the code I posted. You should write public classes and tool classes first. Again: data layer class - > logic layer class - > presentation layer class. Some pictures after the program is running:

Usertypeenum class:
