Storing values in enum

Hi!

My problem is the following: I have a class with a (not static) enum in it that represents 6 values. If I now create an instance of this class, are the values in the enum independent from the values in other objects?


Life is full of choices. Sometimes you make the good ones, and sometimes you have to kill all the witnesses.

So I gather that your enum is defined as an inner class? If so, by definition per the JLS, inner Enum classes are implicitly static inner classes and so the enum's values are the same everywhere. In recognition of their being a static inner class, you need to access the enum from the outer class name and not an instance variable name:

Per the JLS, section 8.9:

Nested enum types are implicitly static. It is permissable to explicitly declare a nested enum type to be static.

Yes, that's exactly what I tried to do. Okay, so I'll change my implementation to a Map instead.
Enums are still new (and quite confusing) to me
