generics

Hi all, I seem to have a bit of misunderstanding with Java Generics and I hope you can help me. I tried to create a map like so:

Map<Debater, int>

(Debater is an Interface I declared) but java complained about the int, so I did:

Map<Debater, Integer>

I suppose it's because int is not a class while Integer is, is this correct?

Also, Now I get a Debater and I need to add 1 to its value in the map. How do I do that?

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping. I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting… >>> More
