The most commonly recognized major classes of polymorphism are
* ''[[Ad hoc polymorphism]]'': defines a common interface for an arbitrary set of individually specified types.
* ''[[Parametric polymorphism]]'': when one or more types are not specified by name but by abstract symbols that can represent any type.
