Agile Java Questions

Agile Java job Interview Questions, a user submitted / interview experience direct from the desk of job interview. These Questions how ever not exactly how they appeared but have been recalled from the memory to provide some idea for candidates who are going for such interview.

This should benefit most of the candidates, Java is a very important programming language most of the time you will face questions on this language. Job seekers attending Java based job interviews should prepare well and try to solve as many problems and look into as many questions as possible and try to solve them on your own and understand the way interviews are done, which are bit different from normal college test/exams.
