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

A little variant of manveru's solution which dynamic create different kind of object based in an array of Class types. Not really different, just a little more clear.

Species = [Dog, Cat]

Species.each do |specie|
  animal = specie.new   # this will create a different specie on each call of new
  print animal.MakeNoise + "\n"
  animal.Sleep
end
