Anjali,
There is no need to apologize. I just wanted to make sure that people understand that it is OK to paste my questions on this message board as long as the source of the question is identified. Anytime a slightly altered version of one of my questions appears without mentioning the source of the question, then I start to wonder if another web site might be using slightly altered versions of my exams.
Thank you for using my exams, and please feel free to discuss the questions here at the
Java Ranch.
