/*************************************************************************
 *  Compilation:  javac Divisibility.java
 *  Execution:    java Divisibility X Y

 *  % java Divisibility 14 21
 *  true

 *  % java Divisibility 100 200
 *  false
 *
 *  a % 7 is the remainder when you divide 7 into a. If the remainder
 *  is 0, then a is divisible by 7.
