FizzBuzz

Introduction
FizzBuzz is an exercise that iterates from one to one hundred print "Fizz" for every multiple of 3, "Buzz" for every multiple of 5, "FizzBuzz" for every multiple of 15, otherwise print the number.

The Exercise
The FizzBuzz exercise is not new to me I first encountered the task in Professor Altenberg's ICS 241 course. I wrote two versions of FizzBuzz, the first version FizzBuzz, is something similar to what Professor Johnson wrote in class, the second version FizzBuzzTwo, is a program I conjured up. Unfortunately, I did not keep track of how long FizzBuzz took to write however, I do know it took less than thirty minutes, FizzBuzzTwo took six minutes to write. FizzBuzzTwo makes use of more than one print statement which is not a good way to output values from a method in Java. FizzBuzzTwo runs the entire program in the main method but for unit testing purposes it would be easier to build a separate method for the conditional part of the FizzBuzz problem. So the code in FizzBuzz is better than FizzBuzzTwo because it returns values after checking the conditions and it is easier to test thanks to the fizzBuzz method.

Issues

There were no problems encountered with Eclipse, was introduced to Eclipse in Mike Paulding's ICS 211 class, the only issue was reacquainting myself with Java. There was difficulty in recalling which String method to use when trying to convert an integer to a String. The dilemma with which method to use was solved by checking the String class section in the Java API .

Conclusion

FizzBuzz is a very good exercise at checking for a programmer's competence. The task was an eye-opener for me and a good reminder to limit the use of print statements. The FizzBuzz exercise, I think, showed how to take advantage of the tools available for use. My uncertainty of the String method forced me to check the API to find a solution to the problem. I expect that many a issue in software engineering and this class will be solved by using Google, API, teammates, etc.
