Module 24

Lists inside objects

Objects that keep a list of their own. A list as an instance variable, created in the constructor; methods that add to the list, go through it, print it, empty it and remove from it; totals and searches over the objects on the list; and rules the object checks before it adds anything. The start of MOOC part 6.
