It only makes sense to know Java specifically if you have some use for it. The limited Java I know is only because I do some work with JVM languages and it becomes a hindrance to not know any. Otherwise, I could have gotten by just fine without knowing it at all. I think it might be better generalized as knowing some object-oriented C-like language (C++, Java, C#).
