Recitation 9 Exercises (7-8 November 2012)

Question 1 Come up with an idea for an object that has three attributes (adjectives), and three actions (verbs). You can write this as a Java class, or just an English description (that you will convert to Java during recitation). For example, an elephant has a weight, trunk length, and playfulness. It can honk, spray water, and stampede. Ultimately, the attributes will become instance variables, and the actions will become methods in your Java class.

Question 2 Come up with a second object that uses your first one. This should also have three attributes/parts and three actions. For example, a circus uses elephants. So one of the instance variables in a circus class might be an array of elephants.
