Course Description

This course is an introduction to fundamental data structures in Computer Science. These data structures, and the algorithms that go with them, make up the standard toolkit for programmers regardless of language and application. We will use the Java programming language for representing both the data structures and also for developing simple programming projects that put them to use. Expect to do a significant amount of programming, as well as paper and pencil exercises.

Learning Objectives

After successful completion of this course, students will be able to:

Teaching Approach

There are two lectures per week in addition to a recitation on Fridays. Lectures will cover topics on the board, along with some livecoding.

Class time will occasionally feature code review, where I talk over bits of student code from the homework to highlight good choices and point out possible improvements. Code review is anonymous, and no one will know which code is yours (maybe not even you!)… but if you’re uncomfortable with the possibility of your code being critiqued in front of other people, please let me know.

Our schedule is on the home page.

There will be an in-class midterm in week 8 of the term, right before spring break. According to the Spring 2022 final exam schedule, our exam is 8am-11am in X-X-218B on 5/12/2022, i.e., in our classroom (McLean 218B) on Thursday, May 12th.

Course Materials

Textbook(s): Elliot B. Koffman & Paul A.T. Wolfgang, Data Structures: Abstraction and Design Using Java, 4th Edition, Wiley, ISBN: 978-1-119-70359-4

There will be slide PDFs available online as a support tool, but they won’t necessarily correspond in a one-to-one way with what we talk about in the course.

Some unsolicited advice on notes: I did not take notes during college, and I regret it. Taking notes is a very useful activity even if you never look at your notes. The act of writing something down in your own words helps you remember it.

Course Requirements

Late work

Homework is due on Thursdays at 11:59pm ET. Late homework will lose points: 2% for each hour late (rounded up). (After 50 hours, late work will not be accepted. We are always willing to give feedback, though.) If you know you will not be able to meet a homework deadline, let us know sooner rather than later.

Quizzes and exams are all time sensitive. If you miss a quiz or need to make alternate arrangements, let us know as soon as possible. The later you ask, the less flexibility we will have.

Grading Procedures

There are 100 possible points that a student can earn in this course. Percentages are listed below.


Each homework and quiz has its own internal “point total”, but these are only locally relevant: each homework is worth the same as the others; each quiz is worth the same as the others.

Academic Integrity

Undergraduate Honor System

Enrollment into the undergraduate class of Stevens Institute of Technology signifies a student’s commitment to the Honor System. Accordingly, the provisions of the Stevens Honor System apply to all undergraduate students in coursework and Honor Board proceedings. It is the responsibility of each student to become acquainted with and to uphold the ideals set forth in the Honor System Constitution. More information about the Honor System including the constitution, bylaws, investigative procedures, and the penalty matrix can be found online at

The following pledge shall be written in full and signed by every student on all submitted work (including, but not limited to, homework, projects, lab reports, code, quizzes and exams) that is assigned by the course instructor. No work shall be graded unless the pledge is written in full and signed.

“I pledge my honor that I have abided by the Stevens Honor System.”

Reporting Honor System Violations.

Students who believe a violation of the Honor System has been committed should report it within ten business days of the suspected violation. Students have the option to remain anonymous and can report violations online at

Learning Accommodations

Stevens Institute of Technology is dedicated to providing appropriate accommodations to students with documented disabilities. Student Counseling and Disability Services works with undergraduate and graduate students with learning disabilities, attention deficit-hyperactivity disorders, physical disabilities, sensory impairments, and psychiatric disorders in order to help students achieve their academic and personal potential. They facilitate equal access to the educational programs and opportunities offered at Stevens and coordinate reasonable accommodations for eligible students. These services are designed to encourage independence and self-advocacy with support from SCDS staff. The SCDS staff will facilitate the provision of accommodations on a case-by-case basis. These academic accommodations are provided at no cost to the student.

Disability Services Confidentiality Policy

Student Disability Files are kept separate from academic files and are stored in a secure location within the office of Student Counseling, Psychological & Disability Services. The Family Educational Rights Privacy Act (FERPA, 20 U.S.C. 1232g; 34CFR, Part 99) regulates disclosure of disability documentation and records maintained by Stevens Disability Services. According to this act, prior written consent by the student is required before our Disability Services office may release disability documentation or records to anyone. An exception is made in unusual circumstances, such as the case of health and safety emergencies.
