classes.rb

# Code challenge!
#
# 1. Save the contents of this gist in a
#    file named classes.rb
#
# 2. Define the initialize method for class B
#    so that, when you run `ruby classes.rb`,
#    the output in the terminal is `true`
#
#    (Don't define any other methods or
#    change existing ones!)
#
# Some terms to search for when attempting
# this challenge: class method, instance method,
# inheritance, super.

class A
  def initialize(message)
    @message = message
  end
end

class B < A
  def self.create(message)
    new(message + '!')  
  end
  
  def message
    @message
  end
end

b = B.create('hello')
puts b.message == 'HELLO!'
