Page 1 of 7 The tech job market is very
active these days, particularly in the developing world. Techies seem to be jumping jobs left, right and center.
Naturally the most discussed topics in developer circles are jobs and job interview questions.
During discussions with a few developer friends, we came up with this idea of creating a databank of frequently asked
interview questions (FAQs).
The
easy way to create this interview questions databank, is to ask as many
people as possible to share the questions they were asked or the
questions that they asked.
If you wish to share Java Interview Question/s, please
add a comment to this particular item.
Please copy paste the following format and add your comment.
We will later compile all data into any easy to use format, mostly an
Excel sheet.

Questions & Answers:
(Update: Aug 06) - Comments over the past year suggest that in Java questions 1) Interfaces 2) Abstract classes are easily the most popular topics. While for web applications questions related to request, session and application scopes are popular.
For questions on:
