// The ListIterator interface allows access of a position in a linked list.
// This interface contains a subset of the methods of the
//  standard java.util.ListIterator interface. The methods for
//  backward traversal are not included.

public interface ListIterator
{
   //Move Moves the iterator past the next element.
   Object next();

   // Tests if there is an element after the iterator position.
   boolean hasNext();

   // Adds an element before the iterator position
   // and moves the iterator past the inserted element.
   void add(Object element);


   // Removes the last traversed element. This method may
   // only be called after a call to the next() method.
   void remove();

   // Sets the last traversed element to a different value.
   void set(Object element);
