Implement a new class named TwoWayLinkedList that uses a doubly linked list to store elements. The MyLinkedList class in the text extends MyAbstractList. Define TwoWayLinkedList to extend the java. util. AbstractSequentialList class. 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. The former sets the cursor to the head of the list and the latter to the element at the specified index.
