Q
What types of members does a subclass inherit from its parent class in Java?
A
A subclass inherits all public and protected methods/variables, as well as package-private (default) members only if they are in the same package. It never inherits private members.
2
Q
True or False: A subclass inherits private members from its parent class.
A
False. Private members remain hidden in the parent and are not accessible to the subclass.
3
Q
Explain the transitivity of inheritance in Java using the following code:
A
The Rhinoceros class inherits from Mammal, which in turn inherits from Animal. Thus, Rhinoceros indirectly inherits from Animal, demonstrating transitivity.
4
Q
Given the hierarchy Rhinoceros → Mammal → Animal, is a Rhinoceros object also an instance of Animal? Why?
A
Yes, due to inheritance transitivity. Since Rhinoceros extends Mammal, and Mammal extends Animal, a Rhinoceros is also an Animal.
5
Q
In Java, under what condition can a subclass inherit package-private (default) members from its parent?
A
Only if the subclass and parent are in the same package. Otherwise, package-private members are not inherited.
6
Q
Which keyword in Java explicitly prevents a member from being inherited by subclasses?
A
The private keyword. Subclasses cannot inherit private members.

What types of members does a subclass inherit from its parent class in Java?
A subclass inherits all public and protected methods/variables, as well as package-private (default) members only if they are in the same package. It never inherits private members.
