package basic; 

import java.util.ArrayList; 
import java.util.List; 

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration; 

public class Runner { 

    public static void main(String[] args) { 

     SessionFactory sessionFactory = new Configuration().configure("/basic/hibernate.cfg.xml").buildSessionFactory(); 
     Session session = sessionFactory.openSession(); 
     session.beginTransaction(); 

     List<Student> students = new ArrayList<>(); 

     students.add(new Student("Michael")); 
     students.add(new Student("Dave")); 
     students.add(new Student("Tom")); 
     students.add(new Student("Dinesh")); 
     students.add(new Student("Lakshman")); 
     students.add(new Student("Cruise")); 

     session.save(students); 

     session.getTransaction().commit(); 
     session.close(); 
    } 

}
