How do you do polymorphism in Ruby?

Question

In C#, I can do this:

class Program
{
    static void Main(string[] args)
    {
        List animals = new List();

        anima         


        

Answer 1

Using idiomatic Ruby

class Animal
  def sleep
    puts "#{self.class} is sleeping"
  end
end

class Dog < Animal
  def make_noise
    "Woof!"
  end
end

class Cat < Animal
  def make_noise
    "Meow!"
  end
end

[Dog, Cat].each do |clazz|
  animal = clazz.new
  puts animal.make_noise
  animal.sleep
end
