Can you use an EnumSet?
You don't say how you intend to use your hierarchy of enums.
Thank you. I rephrase my question as following:
I need to have two Enum types. Most elements of the two are the same,
but there are some different ones.
CarModelA, CarModelB, CarModelC, CarModelM
CarModelA, CarModelB, CarModelC, CarModelX, CarModelW
I just hate to code "CarModelA, CarModelB, CarModelC" twice inside the
two enums. I am wondering if there is a better way to do it.
My first thought (and maybe my second, too) would be to
wonder why you need two separate enums for what looks to be
two subsets of values of one enum. In other words, why not
just have one "enum CarModel" with all six constants?
(Vague general impression: enums were underused before they
showed up in Java, but have been overused ever since.)
