In the address class part 1 Jason uses this: def tos(format = 'short') address = '' case format when 'long' address += street1 + "\n" address += street2 + "\n" if !street2.nil? address += "#{city}, #{state} #{postalcode}" when 'short' address += "#{kind}: " address += street1 if street2 address += " " + street2 end address += ", #{city}, #{state}, #{postal_code}" end address end end Question: Why would you use the address += street2 + "\n" if !street2.nil? in the long and not in the short (below it... it seems he uses a regular if...end) Can you use the 'long' version in both?? Is there a reason behind why those 2 formats?? thanks,

Address 'short' and 'long' if stmt question - easy probably

In the address class part 1 Jason uses this: 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

Question: Why would you use the address += street_2 + "\n" if !street_2.nil? in the long and not in the short (below it... it seems he uses a regular if...end)

Can you use the 'long' version in both?? Is there a reason behind why those 2 formats??

thanks,
