This is a qstn, which most people donot answer when asked.
Maha posted similar (almost same) qstns when he was taking
the exam, but there are not many responses....
http://www.javaranch.com/ubb/Forum24/HTML/001382.html My 2 cents, would be that the system will be programmed to
accept all the possible choices. Strings with "", class
definitions with {}. Who knows what the other person will
type. So the
test program should be designed that way.
Personally, for strings, I would not give the " ". If I am
asked to make a class declarations with the given keywords,
I would not put the {}.
Not sure if this helps, but I thought I will start the
discussion...
I hope others, who took the exam may add.....
Best of luck.

Regds.
