Problem:

Describe and give an example of each of the following types of polymorphism:

- Ad-hoc polymorphism
- Parametric polymorphism
- Subtype polymorphism

Ad-hoc polymorphism

• Allow multiple functions that perform an operation on different
• add(int, int) and add(str, str) would be separately implemented

Parametric polymorphism

• This allows a function to deal with generics, and therefore on any concrete definition of the generic.
• e.g. A List type in Java, regardless of which objects are in the list

Subtype polymorphism

• This allows subclass instances to be treated by a function they same way as it would superclass instances
• e.g. Instances of Cat will be operated on a function the same way as instances of it's superclass Animal.
