Question

Could somebody assist me with me? I'd very much appreciate it

*24.3 (IMPLEMENT A DOUBLY LINKED LIST) The MyLinkedList class used in Listing
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> {
E element;
}
Node<E> next;
Node<E> 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<E> (see Figure 20.40). The former sets the cursor to the
head of the list and the latter to the element at the specified index. Test your new class
using this code from https://liveexample.pearsoncmg.com/test/Exercise24_03.txt.
