Answer Posted / rathnakar

--> Java follows Super Class Object and Sub Class reference
at runtime to excute inherited and overridden methods.

--> Java doesnot support multiple inheritence by using
classes.becoz java compiler gets ambiguity if one method
is defined in many child classes. this happens due to
above reason

--> so execution fails . but it can be achieved using
interfaces. becoz it method over riding and every child
class is identified uniquely w.rt to interface.
