Java interface Start/Stop already exist?

Question

Does an interface with this contract

start();
stop();

Already exist?

I have the impression to recode something classic here...

Answer 1

I don't think so, but I'd say even if it does, it'd be much handier to write your own just in case in the future you need to amend it and add a pause(); or similar.

Answer 2

org.springframework.context.Lifecycle

Answer 3

No, at least not without including additional packages, but it's quite easy to create one:

public interface StartAndStoppable { //I am *terrible* at coming up with names :P
    public void start();
    public void stop();
}

This is good because you can also add new methods if needed later.
