wrong arguments given in an instance of class

I am initialize a variable and set to a new instance of the class Address, I checked if all the arguments are passing and it's saying that wrong number of arguments given 0 expected 6.

address.rb
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



address = Address.new
address.kind = "kind"
address.street_1 = "123 hello"
address.street_2 = " "
address.city = "denver"
address.state = "colorado"
address.postal_code = "12345"

You need to pass arguments to the constructor (ie. Address.new(arg1, arg2, arg3, arg4, arg5, arg6)), and not assigning values to properties on an instance of an object.
