Syntax and usage of enumerations in Java

In the company code, with a lot of enumeration, I am very confused to see. Let's start by looking at how enumerations are written and how to use them. First, the enumeration of the wording of the enumeration, online a lot of this knowledge. Here is a code for the enumeration class that I write myself directly.
