Polymorphism Question

[Erik Ponder]

Hi, I have been testing myself on Polymorphism concepts, and came across this question

Which of the keywords above are often used with polymorphic methods?
a. final
b. abstract
c. virtual
d. static

answers:
a) a
b) b
c) c
d) a, b, and d
e) a, b, c, and d

My initial thought is that a (final) and d(static) are not used with polymorphic methods (final cannot be re-defined, and static is not part of the instance, but to the class itself), but to my knowledge you can use abstract and virtual methods for polymorphism.  So couldn't the answer be (b) or (c)? Would someone be able to provide the answer or provide some clarity here? Thanks

Are you sure virtual is a valid keyword in Java?

Also, when you post something that you came across elsewhere, whether in a book or website or wherever, please cite your sources.

Wow, I was too focused on the concept that I forgot that java does not use the virtual keyword . Thanks for pointing this out to me
