Head First Ruby (Jay McGavren (著)、O'Reilly Media)のChapter 2.(Methods and Classes: Getting Organized)、CODE MAGNETS(No. 1160)を取り組んでみる。

コード(Emacs)

#!/usr/bin/env ruby2.2
# -*- coding: utf-8 -*-

class Blender
  def close_lid
    puts "Sealed tight!"
  end
  def blend(speed)
    puts "Spinning on #{speed} setting."
  end  
end

blender = Blender.new

blender.close_lid
blender.blend("high")

入出力結果(Terminal)
