Lectures

CS2110 has the twice-weekly lectures. Attendance is required. Our discussion of material that may be in the optional book is different, and sometimes the material we cover is not covered at all in the textbook.

Lecture notes are usually posted the day/evening 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/phone). During the lecture, we use not only the ppt slides but also Eclipse, DrJava, and the web, and when we are not using the ppt slides it will be useful for you to have them to look at.

Recitations

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.

CS2111

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. Adrian Sampson and David Gries will be teaching it. Students taking CS2111 must ALSO attend the main lectures and a recitation section. You must be enrolled in ENGRD/CS2110 in oder to take CS2111.

Weekly PDF files for the materials covered in CS2111 are posted on the course CS2111 website ---get to it from a link on the Links page.

Course text

We spent a good part of the summer of 2017 significantly enlarging the JavaHyperText, which can be fviewed as an online text for Java, oriented toward how we cover the material. Look at this JavaHyperTextoften; use it as your main source of information about Java.

The optional course text is: Data Structures and Abstractions with Java 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.  Exams tend to focus on things we covered in class.

You do not need the textbook. It is optional. 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. The 4th appears to be a major change.

Lecture schedule

Below is a tentative list of lecture topics, times for handing out and deadlines for submitting assignments, and times for the prelims and prelim review sessions. The order and content of lectures are likely to be changed as the course progresses.
