The MyLinkedList class is a one-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new 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 o) {

element = o;

}

}

Implement a new class named MyTwoWayLinkedList that uses a doubly linked list to store elements.

Hint. The MyLinkedList class in the text extends MyAbstractList. You may define MyTwoWayLinkedList to extend the java.util.AbstractSequentialList class. You need to implement the methods listIterator() and listIterator(int index). Both return an instance of java.util.ListIterator. The former sets the cursor to the head of the list and the latter to the element at the specified index.
