This section presents a linked-list implementation of sorted lists that is derived from the OrderedListAsLinkedList class given in Section . The SortedListAsLinkedList class is introduced in Program . The SortedListAsLinkedList extends the OrderedListAsLinkedList class introduced in Program and it implements the SortedList interface defined in Program .
Program: SortedListAsLinkedList class.
There are no additional fields defined in the SortedListAsLinkedList class. The inherited fields are sufficient to implement a sorted list. In fact, the functionality inherited from the ListAsLinkedList class is almost sufficient--the only method of which the functionality must change is the insert operation.
