    Class (computer programming) - Wikipedia

    In the terms of type theory, a class is an implementation‍—‌a concrete data structure and collection of subroutines‍—‌while a type is an interface. Different (concrete) classes can produce objects of the same (abstract) type (depending on type system). See more

    Overview
