This is one approach. Both have their advantages and disadvantages. It might be a bad idea to use inheritance for immutable instances because now your sharing implementation details across classes. You can give your super class some unique identifier, but as you add more things (i.e. description, identifiers, sub enums, etc.) you now have to consider these changes in overriden java.lang.Object methods like equal() and hashCode() for both performance and maintenance reasons. I like the template approach because this gives me a template to work with, then I can specialize it for what I need. > I also wonder whether its worth doing this when Java is getting > language support for Enums in 1.5.... Perhaps not. There are many of us that are still on, and will be stuck on 1.4, for a while. I my situation, we have to pick and commit to a J2EE application server. J2EE vendors tend to be slow to upgrade Java versions. Thanks for your example and your input, Phillip. [ Enumeration code snipped -pl ] -- Paul Landes [EMAIL PROTECTED]
