Java: T obj; type of obj.getClass() is Class<?> and not Class<? extends T>. why?

Question

In such a function:

 void foo(T obj)

The type of obj.getClass() is Class and not Class<

Answer 1

The basic problem is that getClass() doesn't return the class because its defined at the Object level. i.e. it is mearly defined as a class which extends object. They could have defined getClass() like.

Class getClass() { /**/ }

but instead its

Class getClass()

which means generics has no understanding of what getClass returns.
