Class Basics

Class Basics

A Ruby class is defined with class ClassName ... end, bundling data and behavior into a single blueprint that objects are created from with .new. Class names conventionally use CamelCase, unlike methods and variables which use snake_case. Every value in Ruby, including numbers and strings, is an object of some class.

Note: Ruby class names must start with a capital letter -- this is enforced by the language, not just a style convention.

Example: Class Basics

class Dog
  def bark
    puts "Woof!"
  end
end

rex = Dog.new
rex.bark
