Most specific subclass for a Java object?

I have two classes A and B, where B is subclass of A and A is not abstract. Therefore I can have objects that are instance of A and objects that are instance of B (and therefore of A).

How can I distinguish objects that are only instance of A?

Sure, I can write something like "object instaceof A && !(object instance of B)" but this is a very poor design since I'll need to change the code every time I add new subclasses to A. Better alternatives?

Solution 
  • object.getClass() == A.class
