public class JavaHashSetIterator {
	public static void main(String args[]) {

		HashSet<String> hashSet = new HashSet<String>();
		hashSet.add("Java");
		hashSet.add("HashSet");
		hashSet.add("Java");
		hashSet.add("HashMap");

		Iterator<String> it = hashSet.iterator();
		while (it.hasNext()) {
			System.out.println(it.next());
		}
	}
}

                /* ............... END ............... */
