Today's focus: think about and practice what we've learned so far
- thinking about the objects in our programs, what they represent and can do, and how they interact
- Java's support for this with interfaces, abstract classes, inheritance, overriding, dynamic method binding, etc.
From Problem Set 2
- the design of the PrefixSumListIterator
- the object-oriented design of SyracuseGenerator and SyracuseSearch
From Labs 3 and 4
- why this in those method calls to add listeners?
- what's up with that Runnable interface?
- a closer look at the FiveGuys example
