Polymorphism is the act of overriding methods within a derived class. Suppose you have a class called "CA" with a method "MA" on it - if you were to now create a child class of "CA" and then re-define the method "MA" on it, this would be polymorphism.

It is a commonly used technique when dealing with derived classes as in a lot of cases, the child class will be performing the same actions as its parent, but with a little extra.

In this video I take you through a simple example of polymorphism using the typical "Animal" class. I also demonstrate how you can call the parent-defined method through the use of "super".
