@Josh it's true that Java enums are more object (struct) than scalar value but they are compared like a scalar so you do:

if (season1 == season2) ...

not

if (season1.equals(season2)) ...

Can structs in C# have behaviour? I don't actually know. The "value type" part is more likely about the fact that it can be stored on the stack rather than the heap, which is extremely useful in some instances.

For example: they've ported Git to Java but there are things C can do that Java is nowhere as near as efficient as and one of them is being able to pass 20 byte SHA1 value objects on the stack, which C# can do.

This is an old post, and maybe comments are irrelevant now, however I wanted to question the comparison of enums between Java and c#.

You say that enums within c# are just thinly wrapped ints, and that is correct. Though I think the comparison with Java enums is invalid. By the look of it, Java enums more closely resemble structs in c#, which are value types and therefore immutable. Would you agree?

hi,

First of all. Thanks very much for your useful post.

I just came across your blog and wanted to drop you a note telling you how impressed I was with the information you have posted here.

Please let me introduce you some info related to this post and I hope that it is useful for .Net community.

There is a good C# resource site, Have alook

I suppose it is these sorts of problems that has been driving the interest in Erlang, Clojure and all the rest.

I'd forgotten how Java is dirty.
