Chris Shayan commented on COLLECTIONS-306:
------------------------------------------
I've developed the method myself please test it by other developers, the code
is:
public static Collection subtract(final Collection a, final Collection b,
Predicate p) {
ArrayList list = new ArrayList(a);
for (int i = 0; i < list.size(); i++) {
Object o = list.get(i);
if(!p.evaluate(o)) {
list.remove(i);
}
}
return list;
}
> 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)
