What are some examples of OOP in Ruby?

Ruby is a great language for object-oriented programming. For example, you can create classes, define methods, and instantiate objects.

Can you show me a simple class example?

Sure! Here's a simple class example:

class Dog
  def bark
    'Woof!'
  end
end

my_dog = Dog.new
puts my_dog.bark  # Outputs: Woof!

What about inheritance in Ruby?

Inheritance allows a class to inherit methods and properties from another class. For example:

class Animal
  def speak
    'Hello'
  end
end

class Cat < Animal
  def speak
    'Meow'
  end
end

my_cat = Cat.new
puts my_cat.speak  # Outputs: Meow

Can you explain polymorphism?

Polymorphism allows methods to do different things based on the object it is acting upon. For instance:

class Bird
  def speak
    'Chirp'
  end
end

class Dog
  def speak
    'Woof'
  end
end

def animal_sound(animal)
  puts animal.speak
end

animal_sound(Bird.new)  # Outputs: Chirp
animal_sound(Dog.new)   # Outputs: Woof
