Generics in Java enhance the type safety of your code and make it easier to read. In my last article, I introduced the general concepts of generics and showed examples from the Java Collections ...

Universal generics would allow Java type variables to range over primitive and reference types, making it easier to extend or reuse code across different types. Credit: Aline Ponce ...

Second, these are Java enums, they can and should have methods on them. When I was working with such mechanisms, we duplicated things like the ids of enums in both the database and the code.

As an aside in java (unless something has got waaaaay better with the JIT/compiler) the resulting code you have will be horribly slow because it will box and allocate all over the place.
