How to resolve error in ruby script?

I have ruby script as follows:

class Person
    def initialize(name)
        @name = name
    end

    def aMethod()
        puts "Excecuting aMethod"
    end
end

class Employee < Person
end

e1 = Employee.new("Salunke")
e1.id

after the execution of above script im getting following error:

first.rb:16: warning: Object#id will be deprecated; use Object#object_id

Problem is: There is an id method on class Object, but thats probably not the kind of id you want. It's the object-id of your employee instance generated by the ruby vm . Since thats a pretty common mistake, the id method got deprecated in favour of the more concise object_id. You would have to implement an id method yourself, or, if you really want the object_id, call that method instead of calling id

According to the warning:

Object#id will be deprecated; use Object#object_id

so, replace the id with object_id

e1.object_id

In your example, "e1" is an instance of your class "Employee" (which extend Person)

When you invoke the method "id" (send the message "id" to the object) on the instance "e1", ruby try to call the id method on the whole chain of objects.

The main Object class didn't declare an "id" but an "object_id" method.

As Phelios pointed out, the message is clear enough.
