Program:

            /* ............... START ............... */
                
import java.util.Hashtable;
import java.util.Enumeration;

public class JavaHashTableIterationThroughValue {

	public static void main(String[] args) {

		Hashtable hashTable = new Hashtable();

		// add key value pairs to Hashtable
		hashTable.put("1", "One");
		hashTable.put("2", "Two");
		hashTable.put("3", "Three");

		/*
		 * get Enumeration of values contained in Hashtable using Enumeration
		 * elements() method of Hashtable class
		 */
		Enumeration enumeration = hashTable.elements();

		// iterate through Hashtable values Enumeration
		while (enumeration.hasMoreElements())
			System.out.println(enumeration.nextElement());
	}
}
                /* ............... END ............... */
