myUtil.MyLinkedList.MyListIterator

All Implemented Interfaces:

java.util.Iterator<T>, java.util.ListIterator<T>

Enclosing class:

MyLinkedList<T>

public class MyLinkedList.MyListIterator
extends java.lang.Object
implements java.util.ListIterator<T>

Students don't have to implement Java ListIterator<T> interface for this inner class. Instead, students should implement Iterator<T> Exceptions need to be thrown under the specific conditions except he following: 1. UnsupportedOperationException in remove(), set(T item), and add(T item). 2. ClassCastException in set(T item) and add(T item). 3. IllegalArgumentException in set(T item) and add(T item). * @see ListIterator for details
