Polymorphism vs Overriding vs Overloading

Question

In terms of Java, when someone asks:

what is polymorphism?

Would overloading or overriding be

Answer 1

I think guys your are mixing concepts. Polymorphism is the ability of an object to behave differently at run time. For achieving this, you need two requisites:

1. Late Binding
2. Inheritance.

Having said that overloading means something different to overriding depending on the language you are using. For example in Java does not exist overriding but overloading. Overloaded methods with different signature to its base class are available in the subclass. Otherwise they would be overridden (please, see that I mean now the fact of there is no way to call your base class method from outside the object).

However in C++ that is not so. Any overloaded method, independently whether the signature is the same or not (diffrrent amount, different type) is as well overridden. That is to day, the base class' method is no longer available in the subclass when being called from outside the subclass object, obviously.

So the answer is when talking about Java use overloading. In any other language may be different as it happens in c++
