Welcome to the website for intro programming in Java.
- Sign-up (purchase) a subscription to the custom, interactive text we will be using:
- Sign up at learn.zybooks.com using your JHED login-based email (such as firstname.lastname@example.org, not an alias)
- Enter zyBook code: JHUEN601107SelinskiFall2017
- Sign-up for our (free) on-line Q&A discussion forum on Piazza as soon as possible! Please use your actual full name and JHED login-based email when signing up so we know who you are. Most resources (lecture notes, exercises, assignments), announcements and course updates will be posted there only.
- Download and install the (free) Java SDK and jGRASP as soon as possible. See the Software Downloads section below for links and instructions. You will likely want to use them on your laptops frequently during class sessions.
Resources for Practice & Review
- REQUIRED Java SDK downloads: choose the most recent version of the Java JDK. You don't need NetBeans or JSEE for this course. Install this before you install jGRASP.
- REQUIRED jGRASP website -- install the Java compiler first (see above).
- REQUIRED Checkstyle downloads: tool, configuration file, and documentation: website, JHU notes
- OPTIONAL JUnit download (JGrasp configuration is similar to that for checkstyle), and notes if you're interested in learning more.
Welcome to the Winter 2018 offering of CS107e!
CS107 is the third course in Stanford’s introductory programming sequence. CS106 provides students with a solid foundation in programming methodology and abstractions, and CS107 follows on to give you the skills needed to build computer systems.
There are two major learning goals for the course.
First, to understand how computers represent information, execute programs, and control peripherals.
Second, to master command-line programming tools and the C programming language.
The course builds understanding from the ground up using bare metal programming on the Raspberry Pi. Bare metal programming uses no operating system and few external libraries.
Students will receive a Raspberry Pi and a kit of parts, and all assignments will run on the Raspberry Pi. Assignments build upon each other by adding more and more functionality to a core library. They culminate in a simple personal computer shell using a keyboard and display.
Finally, students do a project of their choosing where they build a complete hardware-software system.
For information about the differences between CS107 and CS107e, check out this FAQ.
All class announcements will be posted on Piazza.
- Lectures: Mon & Fri 11:30 AM-12:50 PM, Room 124, Building 160
- Labs: Tue & Wed 6:30 PM-8:30 PM, Gates B21
- Lecturers: Julie Zelenski, Pat Hanrahan
- CAs: Lenny Truong, Mark Miller, Anna Zeng, Michelle Park
In the readings, K&R is The C Programming Language (Kernighan and Ritchie), and EssentialC is a PDF available via Stanford’s CS Library. A digital copy of K&R is available to Stanford students via Safari Books Online.
Please read the assigned readings before attending lecture and lab. You should also read the guides for each week.
