DoublyLinkedList

[fam2315]

I have an assignment to implement a Dequeue as doublyLinkedList (with methods insert left, and delete right) without a header, and not as a circular linked list

Here is what I have, seems to simple though:

public class Dequeue {
 DoublyLinkedList dll; 
 public Dequeue(){
 dll = new DoublyLinkedList();
 }
 public void insertLeft(Object o){
     dll.insertFirst(o);
 }
 public void deleteLeft(){
     dll.deleteFirst();
 } 
 public void insertRight(Object o){
     dll.insertLast(o);
 } 
 public void deleteRight(){
     dll.deleteLast();
 }
}

Did you write the DoublyLinkedList class yourself?
Does the DoublyLinkedList class have any error checking? If not you will have to add it to your Dequeue class. By error checking I mean what happens when you call deleteLeft on an empty List?

Does it work?
You need to write a test driver to add items to the list and manipulate the list.
