Mastering Java: The Ultimate Quiz for 'Thinking in Java'

Can the final keyword be used with method arguments in Java?

1. It becomes public

2. It is always private

3. Visibility is not affected

4. It becomes protected

The correct answer is: It is always private

A final member variable in Java means that its value cannot be changed once it has been initialized. The visibility of a final member variable is not affected by the keyword "final" itself. It will still follow the access modifier specified. In this case, the correct answer is B because making a member variable final does not change its visibility, it only means that it is always private and its value cannot be changed outside the class or by its subclasses. Options A, C, and D are incorrect because they either mention that the visibility is affected in some way or that the variable will become a different access modifier, which is not true.
