What is the primary use of interfaces in Java?

To share code among unrelated classes
To provide additional security features
To allow the creation of multiple objects of the same class
To dynamically generate new classes at runtime

The correct answer is: To share code among unrelated classes

Interface in Java is used to define a set of methods that a class must implement. Option B is incorrect because interface does not provide any security features. Option C is incorrect because it describes the role of constructors in Java. Option D is incorrect because interface does not generate new classes at runtime. The primary use of interfaces in Java is for code sharing among unrelated classes, allowing them to communicate with each other effectively.
