Hi:
I have been wondering the same. And after performing a search, I still can't get a clear answer.
This link:
http://www.javaranch.com/ubb/Forum24/HTML/008521.html explains they may fall under the general category of "components" listed in the objectives. And in going through the JQPlus exams, they seem to insist, "There will at least be one question on TextArea."
Although I came across this link:
http://www.javaranch.com/ubb/Forum24/HTML/013340.html which seems to contradict that the constructors and methods of components/containers will be tested. This material also, for the most part, falls under the chapters in the RHE book that explain these topics are useful but not explicitly mentioned in the objectives.
I've noticed many of the mock exams carry questions on these components. And they are doing a good part to drag my mock scores down as I really only read the chapters with these topics, I didn't study them. At some point, I'd love to learn all about this stuff, but considering the extent of all we do have to know, it would be much nicer to stick to what's required for now.
Is there someone who can clear this up?
Do we have to know anything beyond layout managers/events for awt?
Any help is greatly appreciated.
Thank You.
