Question 144

Given:

and

What is the result?

    Correct Answer: C

    The 'city' variable is declared as static in the 'Location' class. Static variables are shared among all instances of the class and are not associated with any particular instance. Therefore, setting 'location' to null does not affect the 'city' variable. When the 'Location' object is created, the constructor sets the static 'city' variable to 'San Francisco'. The garbage collection and the nullification of 'location' do not affect the static variable. Hence, when 'Location.city' is printed, it outputs 'San Francisco'.
