Code:

Contact myContact = session.load(Contact.class, new Integer(6));
myContact.setFirstName("new name");
session.update(myContact);

in this method does "session.load(Contact.class, new Integer(6)); " does integer(6) represent the primary key.

I am doing the update like this

Contact myContact = session.load(Contact.class, new Integer(6));
myContact.setFirstName("new name");
session.update(myContact);
session.flush();
session.clear();
