Hi Gennady Shapiro,
Congratulation,
great score in server & documantation!
Can you pl. clarify my one doubt ?
Although we are not using lock for local mode, Do we have to implement full code for lock and unlock in Data class also or only difination in Data class and complete implementation in RemoteData (network class) ?

Hi bravo,
Congratulation.
Can u pl. eloberate your GUI plan ? That is what did u do for future extention ?
thanks
reena k.

Congratulation !
what a great score . You must be prof. developer.
one question if u dont mind ?
did u wrote whole lock and unlock methods in Data class also or only defination(as Data class is used only for local mode)?
Or u kept complete lock & unlock methods in Both classes (Data and RemoteData)?
pl. guide
thanks
reena

Congratulation !
good score.
Excelent score in General consideration.
Did u use Box layout in GUI ?
Can u pl. eloberate your deceision on mode selection ?
What reason did u give for not extending data class ?
thanks
reena k.

That should not happen. mine worked as it is. It hasd to work as java is platform independent. Ofcourse, if your layout manager are not proper, then because of different resolution on different OS setting etc, u may get different result.
What is your layout like ? how many panels are on outermost window (frame)? is your appliication is working while resizing it ?
check all that first. i think u can find your mistake.

thankx peter.

Peter,
your explanation (in Modifying vs inheritance )is really very deep and clear.
I was about to pack my project but now after reading your explanation I got stuck.

Exaclty you mean to say RemoteData class(remote object) will extend Data class ? if that is true then my design is really wrong. u saved me. pl. comment on my design :
Data class implements dataInterface
RemoteData class extends UnicastRemoteObject, implements DataInterface
I have literally replicated Data class methods in Remotedata class(cut-paste), except RemoteData class is throwing RemoteException and implementing lock and unlock methods.
Is this correct or not proper OO design. Can u pl. comment (and guide)?

Hello,
I read your degree(S)!! really how could u manage to pass all these exams ?! If u are in india i would love to meet u.
I have one query since long time i think u can give proper answer. pl. help if possible.
Q: what are the benifits of subclassing data class ? (Actually they says u should show benifis of both alterantive and then explain why u selected particular one.)
So can u pl. tell me theory + for our case "benifis of subclassing ?" (regardless of our choice)
I hope u will solve my prob.
thanks
