	1. What does the fill method do?
	2. Why or when might it be useful?
	3. Should the instance variable have the capitalization it does?
	4. What would be some appropriate Java documentation comments?
	5. What are some likly invariants for the instance variable?
	6. What are some likely preconditions for the constructor and
	the method?
	7. Where are some likely postconditions of the method?
	8. How could you test the class and the method?  Write a test
	case or cases which could detect errors in a faulty implementation.
