mysql - how do i reinsert a deleted record with auto incremented id in hibernate java -

- 

contact contact7 = new contact(7,"jobs", "jobsatapplet.com", "coffeebeans", "0123456789"); contact7.setid(7); //session.update(contact7);  contact contact8 = (contact)session.load(contact.class, new integer(7)); contact8 = new contact(7,"jobs", "javaatapplet.com", "cupertino", "0123456789"); session.save(contact7);  // commits transaction , closes session session.gettransaction().commit(); session.close();

this code, instead of reinserting record 7 inserts new record increments number of records duplicate values.

i not sure trying do, if update existing record, can this:

contact c = (contact)session.load(contact.class, new integer(7)); c.setlocation("cupertino"); session.gettransaction().commit(); session.close();

this is, if contact class has setlocation() method. without mapping , class files can't more precise.
