Most likely they will ask about the most common gof patterns used by j2ee. So I sincerely doubt they will ask about flyweigth or interpreter. What you also have to realize is that they will not go into patterns details, implementations, etc. They'll give you a J2EE element and ask you what GoF pattern it implements, or vice versa. The design patterns is one of the easy part and you get 2-3 questions on it, no more.
Hi Marianna, It's always better to know the concepts of all 23 GOF patterns, eventhough only a handfull of patterns will be asked in the exam. If you have the SCEA study guide by Mark Cade, Just go through it for all the design patterns and that should be enough. My selection for the most popular patterns from an exam perspective will be 1. Abstract Factory 2. Factory Method 3. Singleton 4. Iterator 5. Mediator 6. Observer 7. Proxy 8. Facade Bijan
Thank you guys for your quick responses. I read GoF book twice but I still feel like in a fog. Unfortunately I don't have Mark Cade's book but I expect it to come soon. Bijan: I am going to concentrate on patterns from your list. Ian: Your mock questions are excellent. Gennady: Yesterday I read threads you started on this forum. I feel they'll help me a lot for part 2. Great contribution!
Hey I referred a bunch of books for patterns, incl roberts and cade, the applied java patterns and the GoF book. My recommendation - make sure you understand the motivation, the uml diagram and the collaboration for each pattern. For that GoF is the best. Didn't really look at the smalltalk code. That's where the other books come in handy. HTH.

No matter. Try again. Fail again. Fail better. This time, do it with this tiny ad:
