Answer Posted / vishal arora

This question leads to two things
1. modifier for abstract class or interface
2. modifier for members of abstarct class or interface

For first in abstract class and interface we can have
public , protected and default and not private if it is top
level otherwise private also if it is nested

for point 2
in an interface every member variable is public and final
in an abstract class you can assign any modifier to member
variables
