/prog/'s opinion about some languages

Hey /prog/,

I'm new in this board, so sorry for being a retard.
I'm starting CS at university. After some pseudo-code, we started with Java and Microsoft .NET (Visual Basic...lol)

I had learned some Python, PHP and C++ beforehand by myself, but I'd like to hear your opinion about all the languages I've mentioned, and what languages are worth learning nowadays.

Thanks.
(I know this can lead to a trollfest, so I'm just asking for YOUR opinion)

Watching people talk about Java on /prog/ is amusing. You have two types of people:

(1) The guy sitting in the back of class who feels compelled to share with you that Java is "slow"
(2) The guy who knows all the expert programming functional languages, but nothing practical
