Question

In my ruby class I have to make a user defined class with many variables. SO far I’ve created a class relating to guitars and Ive looked over the code myself for a while and can’t figure out why I am getting errors on line 52/when I try to print out the examples to test the class

# Guitar
# Source code in /classes/person.rb

# Guitar class with instance variables @name, @brand, @type @strings and
# method take_strings.

class Guitar

  # initialize method is called when user invokes Guitar.new.
  def initialize(the_name, the_brand, the_type, the_strings)
    @name = the_name
    @brand = the_brand
    @type = the_type
    @strings = the_strings
  end

  # Define getters.
  def name
    return @name
  end

  def brand
    return @brand
  end

  def type
    return @type

  def strings
    return @strings
  end
.
  def strings=(value)
    @strings = value
  end

  def to_s
    return "#{name}; #{brand}; #{type}; #{strings}."
  end

end


guitars = [ ]

guitars << Guitar.new("Stratocaster", "Fender", "Solid Body", 6)
guitars << Guitar.new("Les Paul", "Gibson", "Solid Body", 6)
guitars << Guitar.new("White Falcon", "Gretsch", "Semi-Hollow, 6)

# Print all guitars
guitars.each do |g|
  print g, "\n"
end

Answer 1

There are several things going on here:

• On line 26, you do not have an end for your def type method
• On line 32, you have a period in the source file; that’s not going to parse, and will cause issues.
• On line 49, you’ve omitted a closing quote after Semi-Hollow
