Hibernate provide the facility to delete one row or multiple row from a table.

Here is an example.

Example:

package net.roseindia.main;

import net.roseindia.table.Department;
import net.roseindia.util.HibernateUtil;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;


public class HibernateDelete{
    public static void main(String []args){
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        Session session=sessionFactory.openSession();
        Transaction transaction=session.beginTransaction();
        int deptId=2;
        Object object=session.load(Department.class,deptId);
        session.delete(object);
        transaction.commit();
    }
}

Output:

Hibernate: select department0_.id as id2_0_, department0_.dept_name as dept2_2_0_ from department department0_ where department0_.id=?
Hibernate: delete from department where id=?
Department record of Id=2 is deleted successfully

Description: This program deletes the row whose deptId
is 2.Create an instance of Object as

Object object=session.load(Department.class,deptId);

Here passing our Table class Department and the deptId. Now you can delete record by calling delete method as session.delete(object);
