In object-oriented programming, finalization is the process of preparing an object for deallocation; strictly speaking, finalization is all parts of object destruction until memory deallocation itself. Finalization is formally complementary to initialization, which is the part of object creation that follows allocation, but differs significantly in practice – see contrast with initialization. Finalization fulfills a similar role as finally in exception handling; in general these are unrelated, but in some cases the behavior is identical, and the case of finally in a coroutine can be considered a form of finalization – see connection with finally. The term "final" is also used to indicate a class that cannot be inherited; this is unrelated.
