Enumerations (or Enums) in Java are a key concept of object-oriented programming (OOP), allowing the definition of immutable collections of constants. More than just a simple set of values, an Enum is a specific class that can have attributes and methods, thus enriching the design of your code. With the final keyword, Java ensures the immutability of constants, a benefit for the security and clarity of code in OOP. We will see how this powerful structure promotes robust code by avoiding errors related to uncontrolled values and by facilitating the maintenance and readability of the code.
