Design Patterns

 

I decided to start study for SCEA part 1 with design patterns, I will post my study notes for each pattern. Let’s start with  listing GoF patterns and j2ee patterns (I don’t find any new patters introduced to jee 5 so all j2ee patterns apply to jee).

Purpose	Name
Creational	Factory Method
	Abstract Factory
	Builder
	Prototype

Structural	Adapter

SCJP 6

From January I'm Sun certified programmer for java se 6, after a week I received the badge and the big diploma in a mail.
I read only from SCJP Study Guide Katherine Sierra, Bert Bates and I use the simulator (free) from examlab.tk, and javaranch forums (very helpful). It was not an easy exam and you must prepare carefully, study each topic with maximum attention.

Next step (4me): SCEA (Sun certified enterprise architect) I will start soon to study for SCEA, I'm not so confident because current scea is outdated the new JEE 6 specs are here from December 2009, but the update certification I think will appear more lately, another concern is about oracle that own sun now how will they modify the scea...will they focus more this certf on their products ? will they constrain further jee evolution to own view ?...and how valuable will be this cert on the market ?
However I think prepare for scea is a very good reason to be motivated to learn essential sw arhitecture topics ...
