Computer Science

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

Even as a language, Java sucks sure it offers a C-like syntax, but it has crappy special non-object types, no operator overloading, unfunny string, list and dictionary handling syntax, and it's STATICALLY TYPED, which means it's a PAIN IN THE ARSE to work with.

Plus it has no higher order functions, and after learning Python, Ruby, Common Lisp, Scheme, Smalltalk and Haskell I just can't go back to working with langauges that don't support FP even a little bit. Hell even in C you can do some kludgery with function pointers if you have to, but Java doesn't give you anything.
