Course Overview

This course is a continuation of CSE142.  While CSE142 focused on control issues (loops, conditionals, methods, parameter passing, etc), CSE143 focuses on data issues.  Topics include: ADTs (abstract data types), stacks, queues, linked lists, binary trees, recursion, interfaces, inheritance and encapsulation.  The course also introduces the notion of complexity and performance tradeoffs in examining classic algorithms such as sorting and searching and classic data structures such as lists, sets and maps.  The course will include a mixture of data structure implementation as well as using off-the-shelf components from the Java Collections Framework.  The prerequisite is CSE142 or equivalent.

Discussion Sections

You will be expected to participate in two weekly 50-minute discussion sections.  The TA who runs your discussion section will grade your homework assignments.  In section we will answer questions, go over common errors in homework solutions and discuss sample problems in more detail than we can in lecture.

Course Web Page

Information about the course will be kept at http://www.cs.washington.edu/143.  Links to course handouts will be kept on this page along with useful links to other class resources.

Course Administrator

Pim Lustig (pl@cs.washington.edu, 616-3225) is the course administrator and will handle many details including registration and switching sections.

Computer Access/Software

The department operates an Introductory Programming Lab (IPL) that is located on the third floor of Mary Gates Hall.  Consultants will be available at the lab to help students with problems.  The recommended software for the course is the TextPad editor for Windows and Sun’s SDK 5.0 compiler for Java.  More information can be found on the class web page.  You are responsible for keeping backup copies of your work, either on your Dante account, floppy disks, or other media. Your files are not retained on the lab machines.  When you use a public machine, be sure to log out when finished.


You will be expected to complete a variety of programming assignments for this course and to take two open-note, open-book exams.  The resulting scores will be combined according to the following weightings:

40%     weekly homework assignments

20%     midterm (in class on Monday, 2/13/06)

40%     final exam (on Tuesday, 3/14/06, 2:304:20)

Using the weightings above, each student’s scores will be turned into an overall score ranging from 0 to 100 percent.  These will be turned into grades as follows:

90%     at least 3.5

80%     at least 2.5

70%     at least 1.5

60%     at least 0.7

If you need to miss an exam, you must contact Stuart prior to the exam to get permission.  Even if you are sick at home, you should be able to call your instructor’s office phone number to leave a message that you need to be contacted.

The weekly assignments will generally be graded on a 20-point scale.

Late Policy

Each assignment will list its due date.  Most will be due on Fridays at 5 pm.  Each student in the class will have a total of five “free” late days (a late day is 24 hours of lateness).  There are no partial days, so assignments are either on time, 1 day late, 2 days late, etc.  Because of this generous late policy, students will not be granted extensions for assignments unless they have some highly extenuating circumstances.  Once a student has used up all of his or her late days, each successive late day will result in a loss of 1 point.  No assignment will be accepted more than 7 days after its due-date.  All assignments must be submitted by 5 pm of the last day of class (Friday, March 10th), whether or not a student has free late days left.

Policy on Collaboration

From the class webpage you will find a link to the department policy on collaboration which will be applied in this course.  You should familiarize yourself with this policy.

You are to complete programming assignments individually.  You may discuss the assignment in general terms with other students including a discussion of how to approach the problem, but the code you write must be your own.  The intent is to allow you to get some help when you are stuck, but this help should be limited and should never involve details of how to code a solution.  You must abide by the following:

  • You may not work as a partner with another student on an assignment.
  • You may not show another student your solution to an assignment.
  • You may not have another student (current or former) “walk you through” how to solve an assignment.

If you are taking the course a second time, you are allowed to submit a previous solution that you authored unless that program was involved in a case of academic misconduct.  For any assignment where academic misconduct was found (whether the case was settled formally or informally), you have to write a new version of the program.
