• 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.
