No problem anymore.  Thanks to the help I received here and digging a little
deeper in my "Beginning Java 2" book by Wrox the problem was isolated.  I
think it was due to not having a constructor method in my class definition.
With the class def shown below, everything is now working fine for me.  The
Description variable must have been null before.

class ItemData
  {
    // Instance variables:
    int Number = 0;
    String Description = new String();
    double Cost = 0.0;

    // Constructor method:
    ItemData()
      {
        Number = 0;
        Description = "";
        Cost = 0.0;
      }   // ItemData() method

  }   // ItemData class
