When you override clone() from Object its visibility should be raised from protected to public. Is the reason for this simply to allow also non-subclasses in other packages to clone your objects ? Or is there another reason for this ? For classes in the same package I can not see that it matters if the clone() implementation is public or protected
I know that since clone() is protected in Object, subclasses of Object can only invoke clone() on its own objects, and not any object. That is not my question.
regards,
Svein

clone() will continue as much as "this" from java perspective.
