class Fruit
   attr_accessor :type, :taste, :flavor

   def initialize(type = nil, taste = nil, flavor = nil)
     @type, @taste, @flavor = type, taste, flavor
   end
end

class Apple < Fruit
   def flesh
     # flesh the apple
   end
end

class Orange < Fruit
   def peel
     # peel the orange
   end
