is it possible to convert from a ruby object to Ruby class...

What does it mean to convert an object to a class?

and, how to find the included classes in ruby program....

ObjectSpace.each_object(Class) do |c|
  puts c
end

What does it mean to convert an object to a class?

Maybe identify the class of an object?

class Dog
end
 
d = Dog.new 
puts d.class   #Dog

Have you tried the code you've entered as being what you'd like to happen? I ask because I think it will do just that:

puts d.class

This line will return "Dog".

Have a look at this description of the methods of the class Object:

http://whytheluckystiff.net/ruby/pic...l#Object.class

All classes have Object as a parent and therefore will have the same methods.

Yes.

I ask because I think it will do just that:

What does 'it' refer to? What does 'that' refer to?

This line will return "Dog".

Hmm...maybe that's why I put "Dog" as a comment on that line.

All classes have Object as a parent and therefore will have the same methods.

My tests are unable to confirm that statement:

class Dog
  def bark
    puts "Bow wow."
  end
end
 
class Cat
end
 
d = Dog.new
d.bark
 
c = Cat
c.bark
 
--output:--
Bow wow.
r1test.rb:14: undefined method `bark' for Cat:Class (NoMethodError)

Based on the error message, it does not appear that all classes have the same methods.

I think he means that all objects support the methods listed on the page he links to.
