SortedSet and Collections.binarySearch

[ninoid]

hello everyone...

I created my type which implements Comparable like
public class Key implements Comparable{
...
}

and i added couple of keys in my sorted set

SortedSet<Key> keys = new TreeSet<Key>();
keys.add(new Key(...));
keys.add(new Key(...));
keys.add(new Key(...));

when i try to binarysearch my sorted set like Collections.binarySearch(keys, new Key());
i have error message:

The method binarySearch(List<? extends Comparable<? super T>>, T) in the type Collections is not applicable for the arguments (SortedSet<Key>, Key)

Can anyone explicitly write how to invoke binarySearch for theese types without error message...

Thanks

Ok, people...
Sorry for my cross thread...

I do not want to hurt anybody but can someone shut discussion for this thread?

I found solution with SortedMap instead SortedSet...
Thanks
