Enthuware

What makes this code compilable anyway?
It uses the instanceof method on classes and not on interface...
and the explanation says that:

The object is not an instance of D.

Well... there is no choice of compilation error among the given options
so we might guess that in this case
it might return false...

Why do you think there should be a compilation error?

Because of a similar case in question: enthuware.ocajp.i.v7.2.838
Where the statement "if(b instanceof Bird) System.out.println("f is a Bird");"
caused a compilation error when b is an instance of a class named "Bat" that is not inheriting
from class Bird.

But here D does does extend from C. The other question explains why you get a compilation error there. Is there something that is not clear?

well, i thought that the reason is something like that but i wasn't sure,
thanks for the patience....

You may ignore it.

'Select 3 options' is kind of a give away here
