Implement HashLinkedList, which is a simple version of the singly linked list class for the buckets of the hash table. In particular, implement the methodsadd(K,V), remove(K), removeFirst(), getListNode(K)

And here is the HashNode Class which may need to implement a clone method

public class HashLinkedList " Fields private HashNodecK, > head; private Integer size; Constructor HashLinkedListo head = null; size = 0; Add (Hash)node at the front of the linked list public void add(K key, V value)( /I ADD CODE BELOW HERE ADD CODE ABOVE HERE
