There is no required textbook for this class. However, you may find the following textbook useful, and it's free: Data Structures in Java for the Principled Programmer, by Duane Bailey.

Moodle forum

In order to receive important course communication, you will need to monitor the CSE 12 Moodle forum. Note: For the CSE 12 Moodle Forum, log in with your UCSD email account name and password, instead of your "cs12" account name. The Account Lookup Tool will tell you your email account name, and your cs12 account name. (If you are a "summer session" student, you will need to sign up for an account, which you can do here.)
