Computer Science

I might be taking a course in Computer Science at a Uni soon, what languages are commonly used @ Computer Science?

I write financial applications for a banking group
Really?

I hate Java too, you know, but unless you're writing client-side software, using C++ is idiotic. Java is popular in the banking industry for a good reason. OMG SPEED is one of the lowest criteria I can think of for financial software.

Of course, I think they should use functional languages.
