How to iterate through Hashtable

import java.util.Hashtable;
import java.util.Set;

public class HashTableIterate {

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 a Set view of the keys contained in this map.
*/
Set<Integer> keys =ht.keySet();

for (Integer key : keys) {
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
