Hi Ahmed,
Welcome to this forum and hope you'll enjoy it.
I got one of the new assignments (URLyBird 1.2.1) and I know it is quite different : while I got a db interface I cannot modify and that I must implement in some new Data class "from scratch", AFAIK you received an existing data class to be improved by modification or extension.
*** Is that ok to modify the signature of the Data class to implement the DataInterface
(e.g public class Data implements DataInterface ) ??
As it seems that you may modify the provided Data class, I don't see any reason,
a priori, why you couldn't make it implement any interface.
Is anybody out there who got the FBN assignment and who could help Ahmed much better ?
I am pretty sure Andrew will do it when he comes back from his sunny beach.
Best,
Phil.
