Why I must have Map

Question

That's all. I understand that Long is an object, and long is a primitve type, so why can't I map an object to a number?

It's because Generics in Java don't (yet!) work with primitives. — Konstantin Yovkov, Jul 29 '15 at 12:17
The only thing you must: read about how stack overflow works; and that people expect you to do prior research. — GhostCat, Jul 29 '15 at 12:20

First of all... Long is not an object, it is a Class.

Now about your question...

In Generics,unlike C#, Java doesn't support primitive type yet.
