Hi Pradeep,
This question doesn't seem to be from our Simulator. Can you please post question id?

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.
