Algorithms, data structures and maths

Hey /prog/ very inexperienced java programmer here (self taught using BlueJ, obviously using a better IDE now). Anyways now that I can essentially program with Java, I want to learn how to program well with Java, and well every other language.

So /prog/ I ask you, have you any books,web resources etc that you found particularly useful for algorithms, maths and the like?

Let me be the first to tell you to READ SICP. No seriously, read it.
