This program uses a variation of a linked list to keep track of the unique words that appear in a file and how many times each word appears.

Create the Linked List

Create a generics$-$based class called UniqueLinkedList as follows:

public class UniqueLinkedList $\{$

$\}$

Your$$UniqueLinkedList class should have the following public abstraction:

public interface ForEachHandler

An internal interface that declares one method:

void callback$($T value, int count$)$

public void insert$($T value$)$

Inserts a new node into this list. If the value that is being inserted is already in the list then do the following:

Do NOT insert a new node.
