What can be said about a final class in Java?

It cannot be instantiated
It cannot have methods
It cannot be inherited
It can only have static methods

The correct answer is: It cannot have methods

A final class in Java is a class that cannot be inherited and cannot have its internal states modified by any external classes. This means that Option A is incorrect as a final class can still be instantiated, but it cannot be used as a base class for any other classes to inherit from. Option C is also incorrect as a final class cannot be inherited by any other classes. Option D is incorrect because a final class can still have non-static methods, but those methods cannot be overridden by any subclass. Therefore, the only correct statement about a final class in Java is that it cannot have methods, which includes both static and non-static methods.
