I have a question... so... the method throws a DuplicateKeyException
but, if the primary key is recNo and the create methods returns this number for a new records (my solution appends the record to end of database file), how to possible generate this exception ???
Thanks again, Laura

If you do reuse record number, how could you check that name/location etc is the same. Therefore you may ignore this exception. Do document your decision in the choices.txt file.
