Answer Posted / nani
If we want share some common features with all we can go for
abstract otherwise we can prefer interface .
i will give good example to understand easily.
Ex: wholesaler has books and stationary(pens & papers)
supplier1 ask for X class books and Pens
Supplier2 ask for X class books and papers.
here both suppliers asking same standard books and different
stationary items.suppose we can take it as by methods, here
here books methods are common to shared by both suppliers.so
book method is non abstract class. so here we can prefer
abstract.
supplier1 ask for X class books and Pens
Supplier2 ask for V class books and papers.
here both suppliers asking different standard books and
different stationary items.
