Answer Posted / suresh
any class which extends with an object class should have a
constructor whether a class is abstract class or not.
if a abstract class is super class to some sub classes,
then the abstract class should extneds with oject class.
EX: abstract class A{
A{
super(); /// it ll give a call to super class
/// super() we can use only in
constructor
}
}
class B extends A{
}
means any class should extnd with super class.
because of this abstract classes are not 100% abstract.
interface is 100% abstract.
