Useful Resources for Java Interviews

Java-Interview-Resources

Introduction
------------
Innumerable Java interview questions are available on the web 
but there are very few sources for quality answers to these questions. 

Even if you do find good answers, it is more important to understand 
the underlying concept than just knowing the answer to that particular question. 
The interviewers may not ask you the questions in the same 
form or words. They may twist the question or ask it from a different 
view point. So don't just mug up answers to specific questions. 

Try to understand the concepts and write a small program to make sure 
that you've understood it well. It will also help you remember the concept well.
