I am getting stack level too deep (SystemStackError) when I run ruby lib/interface.rb and I dont understand why this is happening.

This is my car.rb file:

class Car
  def initialize(color, year, second_hand)
    @color = color
    @year = year
    @second_hand = second_hand
  end

  def color
    return color
  end

  def year
    return year
  end

  def second_hand?
    return second_hand
  end
end

and this is my interface.rb:

require_relative "car"

my_car = Car.new("red", "1988", false)
puts my_car.color

Thanks a lot in advance for your help!

def color
  return color
end

This calls the color method in an endless loop. Try

def color
  return @color
end

Same for year, etc.
