        linkedHashSet.add("Dave");
        linkedHashSet.add("Peter");

        System.out.println("linkedHashSet : " + linkedHashSet + "\n");

        /*
         * Returns an array containing all of the elements in this set. 
         * 
         * This method acts as bridge between array-based and collection-based APIs.
         */

        Object[] objArray = linkedHashSet.toArray();

        for( Object object : objArray )
        {
            String name = (String) object;
            System.out.println(name);
        }

    }
}
