Not sure why this is failing, barring a typo:

Ruby

This code, directly from a book:

class Animal
def initialize(color)
@color = color
end

def get_color
return @color
end
end

animal = Animal.new(“brown”)
puts "The new animal is " + animal.color

results in “undefined method: color”. But aren’t I defining the method
as part of the constructor? Maybe I just don’t understand what I’m
doing… anyhow, help would be appreciated! :slight_smile:

Your method is named get_color, you’re trying to call the method
color. Make sure they match and it should work.

No.
@color = color
just defines instance variable, which can’t be accessed from outside.
You must define reader method:

attr_reader :color

or

def color
return @color
end
