Inheritance / Superclass / Subclass

A Subclass Inherits functionality from its Superclass.
Protocol

Sometimes called an “interface” in some languages.

Especially the ﬁrst 6 to 8 lectures.

Old iTunesU is not a substitute for coming to class!

Questions are best sent to cs193p@cs.stanford.edu
Sending directly to instructor or TA’s risks slow response.
Sorry, but we cannot take questions from auditors (too swamped).

Web Site
Very Important!
http://cs193p.stanford.edu
All lectures, assignments, code, etc. will be there.
This site will be your best friend when it comes to getting info.
