Hibernate(Session Factory)::Doing the same as my Udemy teacher but mine one doesnt work?

I am doing this course from udemy .Just a beginner in spring and hibernate. I tried every method available at internet but not working.Everytime the errors points at "SessionFactory factory = new Configuration()"

   public class CreateStudentDemo {

    public static void main(String[] args) {

        // create session factory
        System.out.println("Project started");
        SessionFactory factory = new Configuration()
                .configure("hibernate.cfg.xml")
                .addAnnotatedClass(Student.class)
                .buildSessionFactory();

        // create session
        Session session = factory.getCurrentSession(); 

        try{
            System.out.println("Creating new student object....");
            Student tempStudent = new Student("Paul", "Wall", "paul@luv2code.com");
            session.beginTransaction();
            System.out.println("Saving the student..");
            session.save(tempStudent);
            session.getTransaction().commit();
            System.out.println("Done!");
        } finally {
            factory.close();
        }

    }

}
