/**
 *	Arithmetic.java
 *	
 *	@author Jeff Ondich 
 *	
 *	This program illustrates numerical arithmetic and a String
 *	operation or two in Java.
 *
 *	1. Compile the class and run main.
 *	
 *	2. Do +, -, *, and / do what you expect them to do?
 *	
 *	3. What does % do?
 *	
 *	4. What happens if you try to enter a non-integer when
 *	asked for a number?
 *	
 *	5. Change the declaration of i, j, and k from "int" to "double".
 *	For stupid historical reasons which I will describe some time in the
 *	remote future, the term "double" is used as the type for variables
 *	that store real numbers.  So if you want to store "2.718", you'll
 *	need a double rather than an int.
 *	
 *	Also, change "getInteger" to "getDouble" both times.  Now run the
 *	program again and see what the five operations do.  How does /
 *	behave differently for ints and for doubles?
