"javac -version" checks for the Java compiler, which is only included with the Development Kit. It's quite possible to have a Java Runtime Environment (JRE) installed already to run other apps/website applets which includes the java command, so you want to specifically want to check for the presence of javac.

java -version gives you the version of the JDK you're running, I guess; where javac -version is the compiler version.

I have no idea above that! Sorry!
