revitalising an old topic, but yes just do what you fancy, my advice is to learn them all at some point anyway (once you know one it really isnt hard to change syntax, its only really the theory that is harder to grasp than the language itself.) I advise, through personal experience of learning Java and C++ as my first languages, that they aren't the best way to go - i thought they were fine at the time, but since seeing python, that teaches the theory without having to worry about the complex syntax of Java especially and the compiling and complex problems/harder debugging of C++ programs.
Just to reiterate, a common misconception that Java is not, nor even slightly, similar to Javascript.
Hope thats helped and you're well on your way by now.
