# Here is how I would implement Fizzbuzz with objects
# The main issue with your class is what's called
# single responsibility principle
# classes should do one thing and be about
# instances of those classes
# the fizzbuzz class should be about the loop
# just solving fizzbuzz individually

class Fizzbuzz

	def fizz?

	def fizzbuzz?
		fizz? && buzz?
