• Mini-lab– Extra programming practice– Occasionally in-class assignments will be graded– Answer questions from lecture

• You will work in groups• Each group should always have a laptop and textbook

• No new material will be covered

Textbook

RequiredJava Programming: From Problem Analysis to Program Design D. Malik, P. Nair ISBN: 0-619-06497-8

Software

• jGRASP– on public lab machines

• All Programs / UNC Courseware / COMP 14– you will install on your machine

• see link from Syllabus on web• this Friday's recitation

Computer Labs

• 8 Labs

• Maintained by UNC ITS

• Locations, schedules, and a map on course web site

• You may do homework there (jGRASP is installed on all UNC lab machines)

COMP 14 Map

Grades

• Programming Assignments 45 %• Homeworks/Quizzes 15 %• Midterm Exam 15 %• Final Exam 20 %• Class Participation 5 %

Assignments

• Assignments are due at 11:59pm on the due date– turn in using Blackboard

• Homework assignments from textbook– practice for exams

• Programming assignments– budget 10-12 hours per program

• design, code, debugging– start early!

Submitting Assignments

• All assignments will be submitted through Blackboard

• All assignments must include the honor code pledge

• Submission Errors– I will email you and give a deadline for re-submitting– Don't change your assignment

• I will look at the file's timestamp to determine if you originally met the deadline

– Not checking your email is not an excuse for missing the deadline

Late Policy• Assignments

– Due at 11:59 on their posted due date.– You have five “late days” to spend over the semester– After you’ve used your late days, no late assignment

will be accepted– After 11:59pm counts as a day late!!

• Exceptions will be made as necessary– Talk to me sooner than later– "I started late and something came up" is not an

acceptable excuse

Exams

• Mid-Term. Monday October 17th in class– Warning: week before fall break

• Final. Friday December 16th at 4pm.– to take the exam at a different time, you must get

permission from your Dean and bring me the blue slip you get from the Dean

Working in the Lab

• Before you open jGRASP and start coding:– read the assignment– think about what the assignment is asking for– review lectures and examples on the topic– write (yes, on paper) your plan for completing the

assignment (i.e., your algorithm)• Talk to me if you’re having trouble at this point

Campus File System Andrew File System (AFS)

• Disk space associated with your Onyen– automatically backed up by UNC

• AFS in the lab– automatically appears as drive H: when you log in

• On your personal machine– you can install the AFS Client– won’t see drive H: unless you’re connected to the network (i.e.,

can access the Internet)

• More information– see External Links on the course Blackboard site

Backup Your Work!

• Backup your work!

• You will lose something at some point– you might have to learn the hard way

• Use your AFS space– use of AFS space is not required, but is recommended

• Search for “backup” in the Windows help

Help!

http://help.unc.eduhttp://help.unc.edu962-HELP962-HELP

• For help on general computer problems, including getting AFS enabled on your laptop or at home

• Also, for free software

Honor Policy

• Don’t cheat!– Every line of code you turn in must be your own.– You can

• talk to each other about the lecture topics• talk about assignment requirements• Hand wave assignment solutions (out loud, or on a

whiteboard)– You should

• do your own assignments -- design and code– You should never

• share code -- it is easy to detect and we will prosecute

• Pledge Form

Send me e-mail

• Put “COMP 14” in subject line

• For example:– COMP 14, I’m lost– COMP 14, This course is too easy

Homework 0

• Hello World– instructions given Friday

• Due Monday (Sept 5th) at 11:59pm• Write java code and turn it in using Blackboard

This Week's Recitation• Bring your laptop!

• We will install jGRASP and the SDK

• We will discuss “Hello World”
