The Ruby Class

class Animal

  attr_accessor :name

  def initialize(name)
    @name = name
  end

  def greet
    puts "Hi there, my name is #{@name}!"
  end

  protected 
    def protected_method
    end

  private
    def private_method
    end
end

Above snippet is example of basic Ruby class.

We use attr_accesor to access & mutate instance variable instead of writing getter & setter.
