Design Patterns

Hi,

I was going through Design Patterns. But I think HFSJ has not covered all type of designs. So if somebody can tell me what kind of designs I should learn and if any tutorials based on them. I have seen questions in mocks based on other design patterns too.

Any help is appreciated.

Thanks
Kalyani.

Hey Kalyani,

These are the links for Design Patterns posted by some rancher.

1) http://corej2eepatterns.com/Patterns2ndEd/index.htm
2) http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html

These are the patterns you have to know for the exam.These are specified in Sun website.
* Given a scenario description with a list of issues, select a pattern that would solve the issues. The list of patterns you must know are: Intercepting Filter, Model-View-Controller, Front Controller, Service Locator, Business Delegate, and Transfer Object.
* Match design patterns with statements describing potential benefits that accrue from the use of the pattern, for any of the following patterns: Intercepting Filter, Model-View-Controller, Front Controller, Service Locator, Business Delegate, and Transfer Object.

Hope this information helps.

It seems like today is my day to clarify

Servlets and JSPs are huge topics - I mean really big

This forum, and HFSJ, are both focused on the SCWCD exam, so we don't cover all the J2EE patterns, but we do cover the patterns that are on the exam. When we created the exam, we picked about 6 J2EE patterns that we felt were the most commonly used in the context of writing Servlets - those are the ones that are on the exam!

hth,

Bert

p.s. BTW we think that the SCWCD objectives do a good job of covering the foundational concepts that are related to Servlets and JSPs - so that if you pass the SCWCD you will have demonstrated a good basic set of knowledge for these technologies.


Spot false dilemmas now, ask me how!

Hi Bert,
If I am not wrong, what does it mean by "hth" on your signature?
Thank you.

From my fresh experience with SCWCD exam, there was a significant number of patterns questions, I've got 100% of them correct (86% overall result) and I've met just four patterns: most often Business Delegate, once or twice Transfer Object, Intercepting Filter and MVC. All the other patterns mentioned in the answers (sometimes really exotic) were used just to distract from the correct answers. So HFSJ book gives quite a sufficient knowledge in this area.
