Today we covered all of Part II except for the Excercises. The focus here was to compare and contrast the Bug and BoxBug classes. We also talked about main classes or "Runner" classes. We found that a BoxBug is a Bug is an Actor is an Object. So, all that BoxBug has to do to make a square path is to override the act() method. All other methods are inherited from Bug or Actor! Exercise 1 is similar to BoxBug: CircleBug turns 45 degrees CW like Bug, not 90 degrees CW like BoxBug.
