Both of the procedures have repeating sections of code: sending an e-mail and adding a log entry.

Task:
*1.Select a design pattern (substantiate your choice) that would allow extrapolating repeating sections of code in separate classes
2.The selected programming pattern must support the appropriate level of abstraction to allow for additional handlers (ie. marketing modules) to be hooked into any business procedure.

Anyone can give me some advise? use which design pattern?
After I choose the specific design pattern, do you think i need to write the code
as well? I not sure what this task want me to do. thanks.

Hi perhapscwk,

The question doesn't ask you to write any code but then I'd double check with whoever set you the work to be sure. As for the design pattern I'd have thought that your own classes/text books will give you a better idea of the sort of answer that is expected here - I presume that you've had some lessons on this stuff?

I go to interview and this question is one of the test question..I fail it.
SO want to know how to answer. thanks.

Ah I see, sorry to hear that and sorry I can't help you here.

Moved to the Software Development Forum - you might get a bit more general exposure here.

Sounds to me like generic programming, maybe combined with Inheritance. This would allow "repeating sections of code in seperate classes" (e.g. addText(string blabla) or setTextFormat(char format)) and have "the appropriate level of abstraction to allow for additional handlers" (e.g. setEMailAddress(string address) or postComment()) to be added.

I don't know, if such an answer was requested, but it's what I would answer in short.

Greetings,
