How to get elements using Enumeration from Hashtable

import java.util.Enumeration;
import java.util.Hashtable;

public class HashTableGetEnumeration {

public static void main(String[] args) {

Hashtable<Integer, String> ht = new Hashtable<Integer, String>();

/*
* Maps the specified key to the specified value in this hashtable
*/
ht.put(1, “java”);
ht.put(2, “jersey”);
ht.put(3, “spring”);
ht.put(4, “c”);
ht.put(5, “php”);

// Returns an enumeration of the keys in this hashtable

Enumeration<Integer> keys = ht.keys();

while (keys.hasMoreElements()) {
int key = keys.nextElement();

System.out.println(” key = ” + key + ” value = ” + ht.get(key));

}

}

}

Output:

key = 5 value = php

key = 4 value = c

key = 3 value = spring

key = 2 value = jersey

key = 1 value = java
