CS2110 centers on the twice-weekly lectures. Attendance is required. We may have in-class quizzes without prior notice. We often cover material in different ways than what is in the book, and sometimes the material we cover is not covered at all in the textbook.

Lecture notes are usually posted the da/eveningy before the lecture.

Please download the lecture notes the evening before a lecture, peruse them to get a sense of what the lecture is about, and then have the lecture notes handy during the lecture (either on paper or on your laptop/tablet). During the lecture, we use not only the ppt slides but also Eclipse or DrJava, and when we are using Eclipse, it will be useful for you to have the ppt slides to look at.


It is important to attend a weekly recitation, which are considered to be part of the required classwork for the course. We often present material in recitation that is required but not covered in the main lectures. You can switch from recitation to recitation but we like to know which one you are in, in case the University needs to contact you. We added some recitations at a late date; please switch to them if you can to balance out the number of students in each recitation. Use add/drop if you switch sections.

Weekly recitation notes will be posted belowas we finalize them.


This 1-credit S/U optional enrichment class is offered for people who are concerned that that CS2110 might move too quickly and would like a bit of additional help understanding the key ideas. Ross Tate and David Gries will be teaching it. Students taking cs2111 must ALSO attend the main lectures and a recitation section. CS2111 is not open to students who are notenrolled in cs2110.

Weekly PDF files for the materials covered in CS2111 are posted on the course CS2111 website.

Course text

Readings refer to the course text: Data Structures and Abstractions with Java, 3rd edition by Frank M. Carrano, Prentice Hall, 2007. ISBN 0-13-237045-X. 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.

You do not need your own copy of the textbook; sharing is fine. You do not need to have access to the e-book; Prentice offers the ebook to people who purchase a new copy, but a used copy of the book is fine. There aren't very many differences between the 2nd and 3rd edition, so you can manage quite well with a used copy of the 2nd edition.
