Encapsulation
1.What is the primary goal of encapsulation in Java?
-
A. To allow multiple inheritance
-
B. To restrict direct access to data and protect object integrity
-
C. To increase code redundancy
-
D. To allow global variables across classes
To restrict direct access to data and protect object integrity

2.How does encapsulation contribute to the maintainability of code?
-
A. By allowing external classes to modify object data directly
-
B. By enforcing modular code design and reducing dependencies
-
C. By eliminating the need for constructors
-
D. By making all variables globally accessible

3.Which Java feature enforces encapsulation by restricting direct access to object data?
-
A. Static methods
-
B. Instance variables with public access
-
C. Getters and setters

4.What is a common consequence of not using encapsulation?
-
A. Increased security of data

5.Why should instance variables typically be declared as private?
-
A. To prevent unauthorized access and maintain data integrity
-
B. To allow direct modification from outside the class
-
C. To improve execution speed
-
D. To make variables accessible to all other classes
