Java Programming Tutorial: Creating a Linked List

What’s the Difference Between an Iterator and a ListIterator?

• add()- method that lets you insert while traversing the list
• nextIndex()- returns an int representing the index of the following element
• hasPrevious()- returns a Boolean value (true or false) indicating whether there is an element in the reverse direction
• previous()- returns the element before the current element
• previousIndex() - if there is an element before the current one, returns the index of that element

First, you will need to create a new file in your text editor. Next, import the classes you will need to use for this program by typing the following in your new text file:

import java.util.LinkedList;
import java.util.Iterator;
import java.util.ListIterator;
