How do I get puts to work on my class?

Question

class X
  def initialize
    @name = "Bob"
  end
  blah blah
end

puts X.new  # I want this to print X:Bob
puts [X.new, X.new] # I want this to print [X:Bob, X:Bob]

Answer 1

Override the to_s method of your class:

class X
  def initialize
    @name = "Bob"
  end

  def to_s
    "X:#{@name}"
  end
end

puts X.new  # prints X:Bob
puts [X.new, X.new].to_s # prints [X:Bob, X:Bob]

Answer 2

You need to have initialize, not init.
