So, how can a concurrent collection be ordered as well as sorted ? (like table 7.9, page 360 in the OCP book)
All sorted collections are ordered -- as the order is the sort order. The reverse is not true though, as ordered does not necessarily mean sorted. In your example, insertion order is not a sort order.
So, any collection that is sorted, is "ordered as well as sorted".
