Polymorphism

In computer science, polymorphism is a programming language feature that allows values of different data types to be handled using a uniform interface. The concept of parametric polymorphism applies to both data types and functions. A function that can evaluate to or be applied to values of different types is known as a polymorphic function. A data type that can appear to be of a generalized type (e.g., a list with elements of arbitrary type) is designated polymorphic data type like the generalized type from which such specializations are made.
There are two fundamentally different kinds of polymorphism, originally informally described by Christopher Strachey in 1967. If the function ...

of polymorphism as an extension to the lambda calculus (called the polymorphic lambda calculus, or System F). Parametric polymorphism is widely supported in statically typed functional programming languages. In the object-oriented programming community, programming using parametric polymorphism is often called generic programming.
In object-oriented programming, inclusion polymorphism is a concept in type theory wherein a name may denote instances of many different classes as long as they are related by some common super class.[1] Inclusion polymorphism is generally supported through subtyping, i.e., objects of different types are entirely substitutable for objects of another type (their base type(s)) and thus can be handled via a common interface. Alternately, inclusion polymorphism may be achieved through type coercion, also known as type ...
