        }
    }
}
//now this is our main class
class Main {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        System.out.print("Enter the roll number of the student: ");
        int rollno = sc.nextInt();
        //create an object of the studentName class
        StudentName my_student = new StudentName(rollno);
        //call the function to tell the name of the student
        my_student.student_name_given_rollno();

    }
