java inheritance

Show all headers | View raw

Hi 

I did a java test recently and one of the questions was on the subject of 
inheritance/ OO design

The idea was there was a "Storable" abstract class which contained a store() method.

There was a IStorable interface 

And then there was 

class Book extends Storable implements IStorable {
   public void save(Book) {
   }

}
The question was how to improve the implementation.

What is the current thinking on extending abstract classes ?

Is that the issue?

Thanks,
