Java help.

The file UnsortedLinkedDictionary.java contains unimplemented methods for a dictionary based
on an unsorted linked list. Implement all these methods.

The java code is below:

import java.util.Iterator;
import java.util.NoSuchElementException;

public class UnsortedLinkedDictionary<K, V> {

public static void main(String args[])
{
// Add you tests here

}
public UnsortedLinkedDictionary() {

} // end default constructor

public V add(K key, V value) {

} // end add

public V remove(K key) {

} // end remove

public V getValue(K key) {

} // end getValue

public boolean contains(K key) {

} // end contains

public boolean isEmpty() {

} // end isEmpty

public int getSize() {

} // end getSize

public final void clear() {

} // end clear

private class Node {
private K key;
private V value;
private Node next;

private Node(K searchKey, V dataValue) {
key = searchKey;
value = dataValue;
next = null;
} // end constructor

private Node(K searchKey, V dataValue, Node nextNode) {
key = searchKey;
value = dataValue;
next = nextNode;
} // end constructor

private K getKey() {
return key;
} // end getKey

private V getValue() {
return value;
} // end getValue

private void setValue(V newValue) {
value = newValue;
} // end setValue

private Node getNextNode()
{
return next;
} // end getNextNode

private void setNextNode(Node nextNode) {
next = nextNode;
} // end setNextNode
} // end Node
} // end UnsortedLinkedDictionary
