end
class Wheel
@brand
def option
Cycle.new
end
end

w=Wheel.new
@brand —>nil
w.option
@brand —>“something”

i need a requirement like above one example.

should not passing any arguments to child object(w.option)
global variable is not allowed.

something like this?

class Cycle
attr_accessor :brand
def initialize
@brand=“something”
end
end
class Wheel
def option
Cycle.new
end
end

w=Wheel.new
puts w.option.brand

thank for the quick reply

sorry i wrote wrong explanation
this is my correct explanation

class Cycle
@brand=nil
def initialize
end
end
class Wheel
@brand=“something”
def option
Cycle.new
end
end

w=Wheel.new
w.brand —>something
c=Cycle.new
c.brand —>nil

w.option.brand —>something

any idea ?
