(Implement a doubly linked list)
The MyLinked List class used in LiveExample 24.5 is a one-way directional linked list that enables
one-way traversal of the list. Modify the Node class to add the new data field name previous to
refer to the previous node in the list, as follows:
public class Node {
E element;
Node next;
Node previous;
public Node (E e) {
element = e;
}
}
Implement a new class named TwoWayLinkedList that uses a doubly linked list to store elements.
Define TwowayLinkedList to implements MyList. You need to implement all the methods defined
in MyLinkedList as well as the methods listIterator() and listIterator(int index). Both
return an instance of java.util.ListIterator (see Figure 20.4). The former sets the cursor to
the head of the list and the latter to the element at the specified index.
