If the only thing that changes is the constructor should I still derive?

Question

I have a class that has everything already implemented but its initialization process is different for every child class.
Is there a better idiom to replace the ctor? Is there something more generic/dynamic that I should use?

Answer 1

Does each subclass really represent a different concept than the superclass? If the only thing that changes is the initialization, and none of the data or later behavior, could you just add parameters to the constructor to control that initialization?

Answer 2

Or use static factory methods. This allows you to have different names for the "constructor" that shows the intent.
