In reply to gangaraju@m:
new created the class handle p1 and c1. by copying the class handle c1 to p1 .
p1 = c1 ;
p1.a will call the parent task. however similar line in polymorphysim will call child task provided the task are virtual in parent/base class.

That cannot be done. You have hidden the parent task a from the child by overriding it. You must use super.a from the child class, or upcast to a parent class variable.
