04. FizzBuzz Program

I haven't programmed in Java in about a year and a half, so when asked to write the FizzBuzz program, the hardest part was remembering all the java syntax.

All in all, though it was a fun project. After seeing how it 'should' be programmed in class as opposed to my 'oh-crap-i-have-a-minute-left' programming style during the quickie quiz, I have a better sense of how to modularize my code.

I also had to look online for a refresher on javadoc conventions.

Time to program and comment: 31 min, 17.5 sec.

* Fizz Buzz program for ICS 413

* by three then it prints "Fizz".  If divisible by five it prints
* "Buzz".  If divisible by both three and five, "FizzBuzz".  Otherwise,
* it will print the number.  Each output is on a new line.
