Iterator.class vs Iterator.class

Question

I wanted to obtain class object of Iterator and discovered that

 Iterator<String>.class

is not valid. This highlighted a question if its possible at all to use

 ".class"

syntax for

Object<T>

kind of objects in Java.

If yes, then how it can be done? If not, what are the alternatives ?

I am doing Mocking for Iterator using Mockito's

Mockito.mock(Class<T>)

syntax.

That is very complicated way of asking the same question. People with this problem may find it difficult to find that question. — DolphinJava, Sep 05 '14 at 19:21

You can't do this because generics in Java are implemented using erasure i.e. you don't get specialized version of your classes for each type parameter used at runtime. Take a look at this answer in case it didn't turn up in your search.

It is not possible. The way that generics are implemented in Java, they only exist at compile time, for the purpose of type checking.
