COM S 228Introduction to Data Structures
Instructor: Ying Cai
Department of Computer ScienceIowa State [email protected]: Atanasoff 201
Office Hours: MW 3:00pm-4:00pm
Course ResourcesCourse management tool: Blackboard Learn
All announcement (e.g., assignments, due dates, and exam location), clarifications and answers to common questions about homework will be made available there
All programming assignments must be submitted electronically via blackboard learn
So make sure you logon (https://bb.its.iastate.edu) and check frequently
My slides: www.cs.iastate.edu/~yingcai/cs228
TAs Shared with Dr. Jia and Dr. Fernández-Baca Please check the syllabus posted on blackboard for the
complete list and their office hours and location
Contact If you need to send an email to the instructor or the
TAs, please begin the subject line with “CS 228”
Text book (optional)
We will mainly rely on lecture notes, which we may or may not post on line and/or on timeFor additional material you may look up books such as Simon Gray's Data Structures in Java, Addison-Wesley 2007 (textbook used for Com S 228 in Fall 2011 and Spring 2012).
What this course is about
Object-Oriented ConceptsSome simple algorithms (e.g., sorting) and their run-time analysisAbstract data types List, stack, queue, tree, heap, map, graph,
etc.)
Implementation of ADT Generics in Java Collection Interface and Iterators
Course ObjectivesAt the end of this course, you are expected to Write and debug well-structured object-oriented
programs of 2000 or more lines of Java code Implement a Java class given a specification, and
apply OO principles such as encapsulation and inheritance
Understand abstract data types (ADTs) and know common algorithms of manipulating these ADTs
Implement basic data structures in Java including expandable arrays, linked lists, trees, heaps, and hashtables
Understand some basic algorithms (e.g., sorting and searching) and perform runtime analysis
Prerequisite: CS 227
The hardest part of this course is to have solid knowledge of what you learned in CS 227No student is allowed to take CS 228 without taking CS 227 first

This is to give you a rough idea, subject to change ...
Homework
We expect to give 5 programming projects All will be posted on blackboard They will be more complex than those from CS 227 Due dates may overlap
Clarification thread The homework specification may include design
issues that require further clarification and it is your job to identify such issues and resolved them, in advance of the deadline
Clarification relevant to all students will be posted on Blackboard in the “official clarification”
Check BB frequently: All clarifications posted more than 24 hours before the assignment deadline are considered part of the homework specification
Homework GradingCompilation and runtime errors
Use JDK 1.6 compiler Code must compile; zero otherwise You lose additional points for runtime errors
Documentation and style are important Count for 10 to 20 percent of each assignment Each class and method must have a complete and
correctly formatted javadoc comment Duplicated code should be removed Use nternal (//-style) comments appropriately (a
comment should precede the code it describes and indented to the same level)
Use a consistent indentation and formatting style (Eclipse: Ctrl-Shift-F)
Submission and feedback
Late assignments In generally not accepted, except that programming
assignments may be turned in up to 24 hours late with a 25% grading penalty. (weekends and university holidays are counted in the 24 hours)
Results will be returned via Blackboard Learn If you feel an error has been made in grading your
assignment, you must make an appeal to the TA that graded it within one week of the date when the results were made available in Blackboard Learn
The appeal should be made during the TA's office hours, or by email if you cannot attend the TA's office hours
Correct submission of an assignment is your responsibility
Detailed instructions will be provided prior to the first due date.
Other Policies
Academic Honesty Students who plagiarize other work in any
part of assignment/tests will receive F as the letter grade for this course, and will be reported to the university.
Disability If you have a documented disability and
anticipate needing accommodations in this course, please make arrangements to meet with me soon.
How to do well in this class
Attend all classes and recitationsDo all homework in a timely mannerUse your resources: instructors, TAs, class notesYou have to write and run your own programsAsk questions
