In programming language theory, subtyping (also subtype polymorphism or inclusion polymorphism) is a form of type polymorphism in which a subtype is a datatype that is related to another datatype (the supertype) by some notion of substitutability, meaning that program elements, typically subroutines or … See more The notion of subtyping in programming languages dates back to the 1960s; it was introduced in Simula derivatives.
