I have defined something like the following in Delphi in the past:

type
  ItemData = record
    Number:integer;
    Description:string;
    Cost:double;
  end;

var
  ItemsArray:array[1..50] of ItemData;


How do I define, populate, and then access an array such as this in
JBuilder?  I've tried creating a new class that only has data members in it
(no methods), but every time I tried to access a data member at run time, I
get a NullPointerException error.

For example, if I do this ...

ItemData[] myItemData = new ItemData[50];
myItemData[0].Number = 575;
myItemData[0].Description = "widget";
myItemData[0].Cost = 29.95;

... I'll get a NullPointerException error.  I no longer have the bit of
source code for the class definition because I gave up, but it looked
something like this:

class ItemData
{
  int Number = 0;
  String Description = new String( );
  double Cost = 0.0;
}


Any idea what I'm doing wrong?  Thanks.
