I was asked this questions in one interview.
Suppose there is a requirement of highly concurrent application e.g. Email application like Gmail where in
say there 100K users accessing the application at the same time.
You are allowed to ask only 3 questions to client which 3 questions will you ask?
Client in this case is company who want the application to get developed. e.g.Google [Disclaimer: Name is
just to give idea. I know what you must be thinking :) ]
I was really confused there can be n number of questions starting with technology, hardware configuration etc. Can some one tell me which can be best suited questions in above case.
SLAs (expected uptime, response times, usage patterns, etc.)
How much can be spent on maintenance (servers/cloud, support)
Expected growth
Budget?
Desired delivery date?
Do you have a pen to sign or will you need one?

what is the best DataBase for a mobile java program ? J2ME
Used DB file outside of .jar file of program
best speed in running query
have more SQL propertise Like Curser, trigger and ...
needed low space (under 1 Mb)
Other things that is needed for run a high speed java program on every mobile device that have a little amount of space and low speed prossesor.
I fear this question has no real answer. There are loads of databases you could use and none of us know the problem nearly well enough to give you a solid answer on this issue. There are countless SQL and NoSQL options for storing data. Off the top of my head, I would recommend looking at mobile-nosql and perhaps this thread.

Our current system is based on a Spring/Hibernate/Java/MySQL stack. We have a relationship with a company for which we will end up doing a portion of the IT work. They are currently building a system using an outside vendor which is based on PHP/MySQL. I would like to make an argument that they should reconsider and switch to a Java-centric platform. My main argument is that we can utilize our current (Java-based) skillset for system maintenance and enhancements, instead of having a system which requires knowledge of both PHP and Java. However, they have asked if there is any technical reason why this couldn't happen.
It would be great if I could bring some technical arguments to table which show the two platforms are incompatible. However, I've googled the differences, and as far as I can tell, there wouldn't be any particular technical issues. For example, we could use web services for the systems to communicate.
So, the question is, is there anything one could say about PHP which makes it either incompatible with or just not as "good" as Java? E.g security, scalability and other enterprise considerations? I know it's a vague question, but it would be very helpful to get some input.

I need to build a mass mail application to send around 20 lacs mail per day. I need some suggestions regarding the technology choice between php and java.
Please suggest.
Either would work.
Java is typically good for bigger projects because it is strongly typed and good for collaboration, but a mass mail application might be simple enough to make that unnecessary.
Most people think of it as easier to do web stuff in PHP, so if you want this to live in a website, you might want to use PHP.

I want to do SCJP certification and dont want to join coaching for that,so need suggestion on
Without joining coaching how to prepare for SCJP???
I did the exam with the only help of the "official book" and the tests it includes. Passed with 90-something%, after reading the book and doing all its exercises a couple of times.
You may also want to check the forums at JavaRanch.
If you have experience with Java, the exam will be relatively easy. If not, I would suggest you to code quite a lot for at least 6 months basic Java programs (console only is ok, no need to go into fancy web sites) to get a good grasp of the language and increase your chances to pass the test.
No need to worry about wasting your times with coaching classes, here i tell you a self study guide i used for my exam, i used scjp 6 certification training lab for my preparation. I got 58 questions as right out of 60 questions with this tool. It may be help for every one.

Most google results for sample questions/problems for java, results in a link directing to mock certification questions. Does anyone know where can i find sample problems for practice ?
Thanks
codingbat has hundreds of Java practice problems. In addition to sheer numbers of problems, it's also great because it has a testing mechanism in place to check if your solution is correct.
They're mostly on the easy category, but it's still good for practice, and you can always challenge yourself by imposing your own restrictions, e.g. recursion when it's not demanded, regex-only instead of traditional string manipulation, "cheating" by using libraries, etc.
Project Euler is popular. There's not much point in being language-specific if your goal is general practice rather than testing detail knowledge.
