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

        /*
         * Returns an iterator over the elements in this set. The elements are
         * returned in no particular order (unless this set is an instance of
         * some class that provides a guarantee).

        Iterator<String> iterator = linkedHashSet.iterator();

        while( iterator.hasNext() )
        {
            iterator.next();
            /*
             * Removes from the list the last element that was returned by
             * next()
             */
            iterator.remove();
        }

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

Output

linkedHashSet : [Dave, Peter, Phil, Rohit, Virat]

linkedHashSet : []
