  10. Re: Trouble with while loop and the use of the Iteration class.

    The searchID holds the the ID field instance in the Product class. It retrieves it through getID method located in the Products class. The ID == searchId is to test and see if the parameter passed...
  11. Trouble with while loop and the use of the Iteration class.
