Superclassing for two classes

[Marwan Adel]

Dear All,
I have a question about the best practice for modelling this case:

Every A is B but Not every B is A

All methods and attributes in B is in A

These rules can not be changed

So what is the best practice for modelling this case:

Creating super class C which both A & B inherits it with more attributes for A
Create class A to inherits class B
Or should I decorate class B with more attributes from class A ?

What is your suggestion ? Considering that both A & B will be store in same DB table ?

Is there an example what A and B are?

In my assignment I have a doctor class, This doctor can provide consultation so he can act as a consultant
Where every consultant is a doctor, While not every doctor is a consultant

Ah since giving away answer isn't allow for assignment. I shall give you hint, don't think class, the word starts with "i"

Thanks I think I got it.
