Question

class Person
  def name
   puts "Dave"
  end
end

puts Person.object_id

There are only two ways of accessing methods :

1) Someclass.method in case of class methods. #where Someclass is a class.

2) and Object.method when the method being accessed is a regular method declared inside a class. and Object is an instance of a class.

It follows the pattern Object.method so, does it mean Person class is really an object?

or object_id is a class method? The latter seems unlikely because class methods cannot be inherited into an instance. but when we do something like this :

a = Person.new
a.methods.include?("object_id") # this produces true

a is an instance of Person class so object_id cannot be a class method.

Answer 1

Yes, Ruby classes are objects:

>> String.is_a? Object
=> true
>> String.methods.count
=> 131
>> Fixnum.methods.count
=> 128
