What is a generic type? Generics are essentially called generic programming. Using generics means that the code you write can be reused by many different types of objects.

Why use generics? Generics are a new way of programming, and program code written using generic mechanisms is significantly more obvious than the messy code that uses Object variables and then enforces type conversions: better readability, better security.

I think the two problems of understanding can fundamentally understand the benefits of generics, but also to really understand and even skilled use of Java generics.
