Java Program (HelloWorld.java)

package com.example;

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

public class HelloWorld {

    public static void main(String[] args) {

        // Create SessionFactory
        SessionFactory factory = new Configuration()
                .configure("hibernate.cfg.xml")
                .buildSessionFactory();

        // Open Session
        Session session = factory.openSession();

        // Display message
        System.out.println("Hello World");

        // Close resources
        session.close();
        factory.close();
    }
