Ruby class methods

Hi Readers,

In this post you are going to learn how to define class methods and how to call those methods.

If you want to define a class method there are two ways.

1. Inside the class by using the self keyword
2. Inside the class by using "class << self"

Refer the below example to get the Info.

  class Person 
      def self.class_method 
        puts "class method invoked" 
      end 
     
      class << self 
        def class_method2; puts "class_method2"; end 
        def class_method3; puts "class_method3"; end 
      end 
    end 
     
    class << Person 
      def class_method4; puts "class_method4"; end 
    end 
     
    # Invocation of class method 
    Person.class_method


Just practice this, i will come back with new concept.
