1  Private voiddeletestudent () {2Session session=hibernateuntil.getsession ();3Student student=NewStudent ();4Student.setsid (2);5       //Open Transaction6Transaction tx=session.begintransaction ();7 Session.delete (student);8 tx.commit ();9 hibernateuntil.closesession ();TenSystem. out. println ("Success OK"); One}
