sjwats / inheritance.rb

Created December 3, 2013 02:24

OOPII - Inheritance - Quick Challenge - write a set of classes that represent a set of animals. There should be a Duck, Cat, and Dog instance that all implement an emote (**hint**: what sound does a duck make?) and a eat method. A constructor that takes a name as an argument should be defined elsewhere.

	class Animal
	attr_reader :name

	def initialize(name)
	@name = name
	end

	def eat
	["Stuff in nature"]
	end

Last active December 30, 2015 02:19

OOPII Class Methods and Variables Quick Challenge: Can you use a hash with arrays as values to validate both the make and model? For example, we can have a Volkswagen Jetta but we can't have a Ford Jetta. Modify the latest Car implementation so that it takes a hash of data.

	class Car
	@@makes = []

	def self.add_make(make, *models)
	@@makes << {make => models}
	end

	def self.valid_makes(make, model)
	index = 0
	match = false
