Henri Yandell commented on COLLECTIONS-306:
-------------------------------------------
I'm missing something here - I don't see where the b list is used in your
proposed method.
It looks like you only use it in the Predicate itself and the commented out
filter method is cleaner.
> Use Predicate in subtract

> It is good idea to use Predicate in subtract method, I've developed myself
> the mentioned method and now I am testing it. I mean we should have following
> methods:
> The one already exist is:
> public static Collection subtract(Collection a, Collection b)
> I offer to have one more which is:
> public static Collection subtract(Collection a, Collection b, Predicate
> predicate)
