Mondays, Wednesdays, and Fridays, 5:30–6:30 pm
155 Dwinelle Hall

Please congratulate Kevin Casey, Kara Gieseking, and Serena Liu, who as the team DERPARCHER slaughtered the opposition and drank the blood of their enemies in the Network Tournament! They win gift certificates to Amoeba Records.

The Final Exam took place Friday, May 17 at 11:30 am in 100 Haas Pavilion. Students in the Disabled Students' Program who requested extra time reported to 320 Soda Hall at the same time.

The exam is open book, open notes, and closed electronics: if we catch you with electronic devices such as cell phones, laptops, or iPods on your person, you will get zero on the exam. Leave them at the front of the room. If your cell phone rings at the front of the room, you lose a point. Please keep your notes under your seat so people passing in front of you don't trip over them.

Review questions for the Final Exam are available. Here are the solutions.

Textbooks

Required: Kathy Sierra and Bert Bates, Head First Java, O'Reilly, 2005. ISBN # 0-596-00920-8. (Either the first or second edition will do.)
Optional: Michael T. Goodrich and Roberto Tamassia, Data Structures and Algorithms in Java, John Wiley & Sons, 2010. ISBN # 0-470-38326-7. (The first, third, fourth, or fifth editions will do, but the second edition is missing several important data structures.)
Warning: The reading assignments given below apply to the second edition of Sierra & Bates, and the fifth edition of Goodrich & Tamassia. If you have older editions, you'll have to figure out the corresponding readings yourself.

Lectures

The following schedule is tentative. There may be changes as the semester progresses, so check here periodically. You are responsible for knowing and keeping up with the readings listed below; there won't be reminders in class.

Labs, homeworks, and projects that are currently available can be accessed by clicking on them. Sadly, there will be no webcasts this semester, but you can access the webcasts from my Autumn 2006 offering of CS 61B through the Webcast Berkeley page provided by Berkeley's Educational Technology Services.

Some lecture notes can be obtained by clicking on the lecture titles (for ASCII) or the PostScript or PDF links (which save paper). Please understand that they are lecture notes, and that they were written so that I would have something to say in class. I write them for me, not you, and I make them available as a courtesy to you. I edit them after class to make sure they say the same thing I said in class. If I receive complaints that my lectures and lecture notes do not differ, I will stop making lecture notes available. For related reasons, I will not make the lecture notes for a class available until after the class has taken place.
