Step 2

Let's extract the logic to find if anyone has a birthday today.

# Person and PersonFileStore classes is same as before.

# This class encapsulates the logic to find out if the birthday is today or not.

# It has no dependency on other objects

class BirthDay

def initialize(month, day)

@month = month

@day = day

end

def today?

(@month.to_i == Date.today.month) and (@day.to_i == Date.today.day)

end

end

pfs = PersonFileStore.new("#{Dir.pwd}/data.txt")

records = pfs.records

records.each do |person|

month = person.birth_month

day = person.birth_day
