Can you show an example of using the commit() method in the context of Hibernate?

In Hibernate, the commit() method is used to finalize a transaction, meaning it saves all changes made within the current transaction to the database.

Example of usage:

Session session = sessionFactory.openSession();
Transaction transaction = null;
try {
    transaction = session.beginTransaction();

    // Create or modify objects
    User user = new User();
    user.setName("John");
    session.save(user);

    // Commit the transaction
    transaction.commit();
} catch (Exception e) {
    if (transaction != null) {
        transaction.rollback();
    }
    e.printStackTrace();
} finally {
    session.close();
}

Here, transaction.commit() saves all changes made in the session to the database. If an error occurs, the transaction is rolled back using rollback()."}]}]}
