Devaka Cooray

Hi, I am Devaka Cooray, an education enthusiast, independent consultant software architect, enterprise software engineer, technical instructor, and a certified Java web and enterprise developer. I am the creator of Examlab, an online OCPJP test simulator. Well, I think that would pretty much define what I am.

Since when I first got my hands on a computer, I've so far involved in various stuff related to web engineering, networking, distributed systems, enterprise components, system integrations, web services, data management, and web security; with lots of cool and fun stuff!

I have worked with several programming languages on many different things, but Java is what attracted me the most, so I think it deserves a special mentioning. That said, unless Java was there, I might probably have never been so much into web and enterprise application stuff.

One of the things I really love to do with computers is creating things and putting them online. The part I love the most in it is where I get acknowledgement from those who have gotten some benefit from something I made. Tell me if you are one of them; I would appreciate :)

I spend most of my day sitting in front of a computer (yeah I know that's bad), messing around with gobs of software engineering. And when I don't, I lika read about all kinds of science and exploration stuff. Thinking about how far the Voyager-1 traveled makes me feel wow!

Javaranch is the most popular Java community outside Sun/Oracle. It has nearly 300k registered users consist of authors, experts, and programming greenhorns! I joined the ranch in 2008 because I liked their friendly atmosphere. After a couple of years, in 2010, I was made a moderator, and I have been an administrator of Javaranch since 2015.

Examlab is an exam simulator for the Oracle Certified Professional Java Programmer (OCPJP) certification. I first created Examlab in 2008 as a Windows-based freeware, with a set of 360 questions. After it reached lots of downloads, I converted it to a web application, which people found to be much more convenient.

University of Moratuwa is where I got my 2012 bachelor's in information technology from. I can just say that it was a really great experience!
