        // Creating an empty Set
        SortedSet<String> set
            = new TreeSet<String>();
  
        // Use add() method to
        // add elements into the Set
        set.add("Welcome");
        set.add("To");
        set.add("Geeks");
        set.add("4");
        set.add("Geeks");
  
        // Displaying the Set
        System.out.println("SortedSet: "
                           + set);
  
        // Removing elements
        // using remove() method
        set.remove("Geeks");
