Hi,
I guess you dont need to know about specific classes. They will describe a scenario and you need to select the best design pattern for that scenario.
for Ex:
You have a set of data that represents the history of price of certain stocks. You are required to present this information in different ways like graphs or simple text etc. to end users.
Which design pattern would be most suitable to handle such requirement?
Ans: MVC
Thanks!

Well, the best place I know to look is the book:
Core J2EE Patterns by Alur, Crupi, Malks
ISBN: 0-13-064884-1
The low-cost (free) solution, is to look at :

I guess Kens/Miftahs notes is good enough for the exam.
Thanks!
