        linkedHashSet.add("Virat");

        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();

        /*
         * Using Iterator to get each element from the LinkedHashSet.
         */

        while( iterator.hasNext() )
        {
            String name = iterator.next();
            System.out.println(name);
        }

    }
}

Output

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

Dave
Peter
Phil
Rohit
Virat
