"javaboy", The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp .

"javaboy" jdk stands for java development kit and sdk software development kit. and what's the difference between two is sdk is the installable version of jdk. if you've jdk then you dont need to install it just copy it in your hard disk. and if you've sdk then you can install it. and after installation it appears as jdk1.x where x is 1, 2 or 3.
