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.

I'm finishing my degree this summer with an IT degree. I had to take several coding courses in C++, Java, HTML / CSS and Python. I never went very deep in all of these languages - just enough to get my feet wet. I felt like I learned concepts more than languages which is good. I'm interested in learning more in hopes of self-training to get a developer job.
Can you point me to books, forums, websites etc... I'm not looking to learn a individual language mow in death just a firmer grasp on programming. Thanks.
Sounds like you need "purpose". The best way to learn programming is to do it with a purpose in mind. If you don't have ideas for a project on which to learn (if its something useful or sellable all the better), then look around for open source projects you are interested. Dig in and start working on it. Explore github or google code for projects that interest you. Down load and study the code, etc.

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?

I have a very basic knowledge of the Java language and how it works from reading the likes of Head First Java and the Dummies book. I've not got to the end of either book as of yet and am really liking the Head First book as it is very useful and clear.
My question though is, what is the best app to make as a first app to help learn Java? Would it be something like a calculator, or maybe a simple address book where you can input people and then search for them to return their data?
I'm just looking to put my knowledge so far to some use and having a bit of trouble thinking what a good App may be for a first app that will really help me as a beginner?
Any help will be much appreciated!!
Thanks

HI
I am a B.E(CS) fresher.I am searching for a job in IT.There are openings for few C++
developers than java developers.Once i get 1-2 years of experience as C++ developer,can
i switch to a java application developer(for survival).
If your smart you can switch to anything. Really.
Specifically regarding programming languages, a language is like a tool used for a particular problem. See yourself as a carpenter rather than a 'hammer operator' or 'saw operator'.
See similar questions:
Learning multiple languages
Sure you can. Just don't underestimate the effort to learn the language well - you will be benefitted by the syntax looking familiar, and flabbergasted at the size of the runtime library.
If you go for this, write a lot of code.
Possible, but the environments/frameworks for each mean they are more different than the cosmetic syntax similarities might suggest. Don't assume they're basically interchangeable.
From an employers point of you I'd say previous 1-2 years experience will not count for much if anything. Friends of mine who have tried this in the past have had to drop a lot in salary and almost start in junior positions again. With only 1-2 years of experience that might not make a big difference in your case.

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.
