Instructions:

There IS a quiz associated with this session's Preparation, but it is NOT in Moodle.

• Instead, follow this link to the Quiz for Session 9.
• You can print the quiz and write your answers on paper (that is probably simplest) or you can write your answers in a separate document — your choice.
• In any case, do the quiz as you watch the videos. The quiz follows the same order as the videos/reading do.

Videos and Reading:

1. What is a CLASS -- the concept
   • Watch this Video [7:44 minutes]. It reviews the concepts of a object and class.
2. What is a CLASS -- the notation
   • Watch this Video [6:56 minutes]. This video reviews the notation of a class, as well as the concepts. It is important preparation for the next video.
3. What is a CLASS -- the implementation
   • Watch this Video [11:43 minutes].
     • This is the new stuff (but the previous videos are super-important preparation without which this video will make no sense).
     • It shows all the basics of how to implement a class, using a Point class as an example.
     • In your in-class on-the-computer exercises, you will do an extended example that starts where this video leaves off.
