Fairly language agnostic, from memory most of those books tend to concentrate on concepts, though they use Java or perhaps C++. I've seen copies in larger libraries and book stores.
I'd suggest looking at O'Reilly Learning / Safari - you get access to a whole heap of books (40,000 last time I looked), videos and all sorts of other things. It is $400 a year. Personally I decided books are so important, and was spending more each year (most books are $60 - $120 each), so I subscribed years ago and have never since thought about the cost.
