Answer: (d).Java

Q65.

Is it possible to have all the abstract classes as base classes of a derived class from those?

Yes, always

Yes, only if derived class implements all the methods

No, because abstract classes doesn’t have constructors

No, never

Discuss

Answer: (b).Yes, only if derived class implements all the methods

Class B

Class C

All together

Discuss

Answer: (b).Class B

Q67.

Why does diamond problem arise due to multiple inheritance?

Derived class can’t distinguish the owner class of any derived method

Discuss

Answer: (a).Methods with same name creates ambiguity and conflict
