   public static void main(String[] args)

   {

       // Set deonstration using HashSet

       Set<String> hash_Set = new HashSet<String>();

       hash_Set.add("Geeks");

       hash_Set.add("For");

       hash_Set.add("Geeks");

       hash_Set.add("Example");

       hash_Set.add("Set");

       System.out.print("Set output without the duplicates");

 

       System.out.println(hash_Set);

 

       // Set deonstration using TreeSet

       System.out.print("Sorted Set after passing into TreeSet");

       Set<String> tree_Set = new TreeSet<String>(hash_Set);

       System.out.println(tree_Set);
