Which among the following two is best and why? Abstract Class and Interface. What is the major diff..

Answer / anitha

a)for Future, we can provide extra services in Abstract
Class ,these futures can able to access all of its
Clients. And also it supports reusability.
suppose the implementer need not provide implementation
for all the methods.

Where as in Interface we don’t have this future(reusability
and extra servicess).
each implementer need to provide
implementation for all the methods and
also we cont provide extra services in
future.The interface should be constant.

b)Interface can support multiple inheritance where as
abstract class does not.
