B) The ability of a class to implement multiple interfaces

C) The ability of objects of different classes to be treated as objects of a
common superclass

D) The ability of a class to inherit from multiple classes

Correct Answer: C. Polymorphism in Java allows objects of different
classes to be treated as objects of a common superclass, providing flexibility
and code reusability.



2. Fill in the Blank: In Java, the process of combining data and methods
into a single unit is known as __________.

Correct Answer: Encapsulation. Encapsulation helps in hiding the
internal state of an object and restricting access to certain components.



3. True/False: In Java, the "final" keyword can be used for variables,
methods, and classes to prevent them from being overridden or redefined.
Correct Answer: True. The "final" keyword is used to make variables,
methods, and classes immutable or unchangeable.



4. Multiple Response: Which of the following statements are true regarding
abstract classes in Java? (Select all that apply)

A) An abstract class can be instantiated

B) Abstract classes can have both abstract and concrete methods

, C) Abstract classes can serve as blueprints for other classes

D) An abstract class may not contain any abstract methods

Correct Answer: B, C. Abstract classes can have a mix of abstract and
concrete methods and can be used as base classes for other classes.



5. Multiple Choice: What is the purpose of the 'super' keyword in Java?
A) It refers to the superclass of the current object

B) It is used for type casting objects

C) It denotes an abstract method in a class
D) It is used to invoke a method in the child class

Correct Answer: A. The 'super' keyword is used to refer to the
superclass of the current object, allowing access to superclass members.



6. Fill in the Blank: In Java, the process of defining two or more methods in
a class with the same name but different parameters is known as
__________.

Correct Answer: Method overloading. Method overloading allows
methods with the same names to perform different actions based on the
parameters.



7. True/False: Java does not support multiple inheritance through classes
but allows it through interfaces.

Correct Answer: True. Java supports multiple inheritance through
interfaces by allowing a class to implement multiple interfaces, but not
through classes.
