What do you call a class that implements an interface?

Question

Let's say class A implements interface B; what can we call class A with respect to interface B? In this case, class A is a "subclass" of interface B (as if B was a class), or is there a special term for implementing the interface, or not?

Thanks in advance

Edit: Alec would agree to answer if that were the answer

Answer 1

"Interface implementation", as a rule, I heard what it is called. I am pretty sure that most developers will understand what you mean when you talk about it.

Answer 2

An “interface implementation” is generalized, and in android we usually call it an “ interface listener class ”. In your case, if A implements the B interface, then it will also implement its methods.

Answer 3

I believe the correct term is a concrete class.

Answer 4

You do not name classes that implement any interface, at least I don’t know any specific term, they just implement a specific set of specifications and property methods, not necessarily having any relation to it in OO terms. People seem to often designate an “implementation of an interface” as “inheriting an interface”, the latter is incorrect and should be used in the correct sense (in fact, when interfaces inherit other interfaces, obviously) to avoid confusion.

TL; DR I think there is no term for him.

Answer 5

We can say: A is an implementation of B

Answer 6

I heard that it is called both "implementation of the interface" and "Concretion".
