java - SortedVector from Vector -

(learning task - got stuck) need create class (sortedvector) extends vector sorting elements. can't figure out how overload addelement method. must utilize collections.sort.

public class sortedvector extends vector { public void addelement(object o){ super.add(o); collections.sort(); //what do here? } }

you want sort current collection - pass this collections.sort:

public class sortedvector extends vector { public void addelement(object o){ super.add(o); collections.sort(this); // note usage of } }
