When address = Address.new is invoked it generates an empty variable address whereas the class Address is called from ./address.rb.
But somehow code challenge keeps telling me that "address" is an invalid variable.
class Address
attr_accessor :kind, :street_1, :street_2, :city, :state, :postal_code
def initialize
@addresses = []
end
def add_address(kind, street_1, street_2, city, state, postal_code)
address = Address.new
@kind = kind or ''
@street_1 = street_1 or ''
@street_2 = street_2 or ''
@city = city or ''
@state = state or ''
@postal_code = postal_code or ''
end
def to_s(format = 'short')
address = ''
case format
when 'long'
address += street_1 + "\n"
address += street_2 + "\n" if !street_2.nil?
address += "#{city}, #{state} #{postal_code}"
when 'short'
address += "#{kind}: "
address += street_1
if street_2
address += " " + street_2
end
address += ", #{city}, #{state}, #{postal_code}"
end
address
end
end

Pro Student 26,794 PointsThe problem is in this block of code.
def initialize
@addresses = []
end
The challenge is asking for
initialize a variable called address which will be a new instance of the Address class.
To initialize a new instance of class, you have to do so outside of the class definition; also, there's no need to make any change the class definition body.
class Address
attr_accessor :kind, :street_1, :street_2, :city, :state, :postal_code
def initialize(kind, street_1, street_2, city, state, postal_code)
@kind = kind or ''
@street_1 = street_1 or ''
@street_2 = street_2 or ''
@city = city or ''
@state = state or ''
@postal_code = postal_code or ''
end
def to_s(format = 'short')
address = ''
case format
when 'long'
address += street_1 + "\n"
address += street_2 + "\n" if !street_2.nil?
address += "#{city}, #{state} #{postal_code}"
when 'short'
address += "#{kind}: "
address += street_1
if street_2
address += " " + street_2
end
address += ", #{city}, #{state}, #{postal_code}"
end
address
end
end
# initialize instance of Address class with arbitrary values
address = Address.new('kind','st1','st2','city','state','zip')
Hope that helps.
