Polymorphism

[Luiz Pereira]

I'm studing about override and overload. I found in books and papers diferent opinions about this subject.
Some authors consider override and overload as polymorphism, others consider olny override as polymorphism and overload as feature of OO.

Is overload one kind of polymorphism?

Thanks.

I am not too sure about this, but I read this somewhere:

In Java,
dynamic polymorphism: Overriding
static polymorphism (if there is such athing in Java): Overloading

[Luiz Pereira]

I work with java too, the Katty's book for certification not consider overload as polymorphism, but, I read others book about java that consider.
