The enum declaration defines a class (called an enum type). The enum class body can include methods and other fields. The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values...

It's a good idea to cache the result of values() inside the enum itself if you use it multiple times. That's because, every time you invoke values() method, it creates a new array. So, that is really not required, as you are always going to get the same array elements. As noted...
All the constants of an enum class can be obtained by calling the implicit public static T[] values() method of that class. Added in 1.5. Java documentation for java.lang.Enum.valueOf(java.lang.Class<T>, java.lang.String). Portions of this page are modifications based on work created ...
