Lecture Notes
Readings refer to the course text: Data Structures and Abstractions with Java, 3rd edition by Frank M. Carrano, Prentice Hall, 2011. ISBN 978-0-13-610091-1. See also the Prentice Hall website for additional material. Readings are intended to be complementary to the lecture: you can do the reading before class, or after class, but should certainly read the chapter at some point to make sure you fully understand the material. Exams tend to focus on things we covered in class.
