Thinking in Java (4th Edition)
Bruce Eckel
I don't like computer books that treat you like a kid: you need to go through chapters and chapters before the author starts challenging you. Not this one. TIJ reads like a conversation, moves fast and is always surprising you with interesting programming snippets. Its actually a lot of fun to read and tough to put down!
Undoubtedly one of the best books I've read in programming.
Read it if you want a non-dumbed down approach to Java.
