Hashtable values Iterator example

This is an example of how to obtain a Hashtable values Iterator, that is an iterator of the values of the Hashtable. Obtaining a Hashtable values Iterator implies that you should:

  • Create a new Hashtable.
  • Populate the hashtable with elements, using put(K key, V value) API method of Hashtable.
  • Invoke elements() API method of Hashtable. It returns an Enumeration of the values in this hashtable.
  • Use the Enumeration methods hasMoreElements() and nextElement() on the returned enumeration to fetch the elements sequentially.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;
import java.util.Hashtable;
import java.util.Enumeration;
public class HashtableValuesIterator {
  public static void main(String[] args) {
    // Create a Hashtable and populate it with elements
    Hashtable hashtable = new Hashtable();
    // Enumeration elements() operation returns an Enumeration of values contained in Hashtable
    Enumeration valuesEnumeration = hashtable.elements();
    // Iterate through Hashtable values Enumeration
    System.out.println("Hashtable values : ");
