    public static void main(String args[])
    {
        // Creating an empty LinkedHashSet
        LinkedHashSet<String> set = new LinkedHashSet<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 LinkedHashSet
        System.out.println("LinkedHashSet: " + set);

        // Displaying the size of the LinkedHashSet
        System.out.println("The size of the set is: "
                           + set.size());
    }
}
