Hi
You may be right .I dont know exactly whether it is from enthuware or online free mock exam or from manning kit or from others.But i have noted it during exam preparation for asking later to someone.
Please give me answer for it.


I dont know exactly from where i noted these but i am doing preparation from these stuff which i have :HFSJ 1.4 ,Manning kit,Enthuware kit and some time also do free online exams .So i dont know exactly from where i noted down these questions.
I make notes while preparing and also mark against them to ask later to someone like on javaranch if i am unable to understand that question.

Sorry for writing source:enthuware because it seems me that it may be from that.
