Hey everyone,

I'm a student at a university in Virginia and it seems that there is a differing opinion on polymorphism between a few of my professors. Some of them say polymorphism through inheritance is the best way to go, while other promote polymorphism through interfaces. I'd like to hear other peoples opinions.

Horses for courses. I think they are probably both right. Most "inheritance" in Java is probably mimicked by implementing interfaces, rather than extending existing classes, however.

Other opinions welcomed; I am used to people disagreeing with me
I agree. Here's the link:
