What alternative do enums have since they cannot be inherited from?

Extending classes
Implementing interfaces
Static importing
None of the above

The correct answer is: Implementing interfaces

Enums in Java cannot be inherited from, so options A and C, which describe a process of inheriting attributes from other classes, are incorrect. Option D is also incorrect because there is another alternative for enums besides inheritance. Rather, enums have the alternative of implementing interfaces, which allows them to define their own methods and attributes while still preventing them from being inherited. This is why option B is the correct answer.
