Students are fully responsible for all material presented in lectures, even if some of it does not appear in these slides. These slides are intended for the lecture presentations; for reference, use the indicated reading (fourth column in the table). An effective strategy is to look over the reading material before the lecture, then study it in detail soon afterwards. We have only begun to build the booksite for the 4th edition, but you might find it useful since it contains links to the Java code from lecture. The fifth column in the table gives links into the booksite.
