Polymorphism in Ruby: A Simplified Explanation
Introduction to Polymorphism
Polymorphism is a core concept in Object-Oriented Programming (OOP). It allows objects of different classes to be treated as objects of a common base class. In Ruby, polymorphism simplifies code by allowing you to work with objects in a generic way, making it more flexible and extensible. In this guide, we'll explore polymorphism in Ruby with simple examples.
In Ruby, polymorphism is often achieved through method overriding. Multiple classes can implement the same method, but each class provides its own specific implementation. Here's an example:
puts "Animal makes a sound."
class Dog < Animal
puts "Dog barks loudly."
class Cat < Animal
puts "Cat meows softly."
In this example, both
Cat classes inherit from the
Animal class and override the
speak method with their specific behavior.
Polymorphism allows you to work with objects of different classes using a common interface. Here's how you can use polymorphism:
animal = Animal.new
dog = Dog.new
cat = Cat.new
make_speak method takes any object that responds to the
speak method, and you can pass objects of different classes to it, resulting in polymorphic behavior.
Polymorphism simplifies code by allowing you to work with objects in a generic way while maintaining specific behavior for each class. It promotes flexibility and extensibility in your Ruby applications, making them easier to maintain and extend.
Practice using polymorphism in your Ruby programs to become a proficient Ruby developer. For more information, refer to the official Ruby documentation.
