Hi,
please consider following example. I want to acces class B by

Method work should print the actual class (B).

Hi,
could you check whether it is correct, that second line in main
failes with a compiler error?
I think the compiler should be able to deduce the type without
explicitly passing it to the method call.
Kind regards

You mistyped the function name, it's getFileName (capital N), and
you forgot return. So:
