Apparently, the most sought after language is Java. Not that surprising considering it powers quite a few things, including Android and anything running Android (well, to a point, I guess since it doesn’t run Java in the same way that you would run the JVM on, say, your desktop.) Still, gives me a reason to brush up on it. And perhaps work towards a Java certification. I did have J2CP, but that was years ago, so I’m not sure if it is even valid any more.
Although it surprises me a little that Ruby and Perl aren’t on this list.
