LinkedList implements LIST Interface
Example
import java.util.Iterator;
import java.util.LinkedList;
/**
* LinkedList implements interface. Implements all optional list operations,
* and permits all elements (including null). In addition to implementing the List interface,
* provides uniformly named methods to get, remove and insert an element ( addFirst, addLast)
* at the beginning and end of the list.
* linkedlists would be used as a stack, queue, or double-ended queue (deque).

Output :
THE VALUE: 0
THE VALUE: 1
THE VALUE: 2
THE VALUE: 7
THE VALUE: 7
THE VALUE: 8
THE VALUE: 3
THE VALUE: 4
THE VALUE: 5
THE VALUE: 6
THE VALUE: 7
THE VALUE: 10
