Hi everybody,
I'm studying for OCAJP 8 certificate with Boyarsky, Selikoff study guide (EXAM 1Z0-808)
In the review questions of the first chapter, question 5 states:

Given the following classes, which of the following can indipendently replace INSERT IMPORTS HERE to make the code compile? (Choose all that apply)



  • A. import aquarium.*;
  • B. import aquarium.*.Jelly;
  • C. import aquarium.jellies.Jelly;
  • D. import aquarium.jellies.*;
  • E. import aquarium.jellies.Jelly.*;
  • F. None of these can make the code compile


  • I answered F because I supposed that all the code was in the same file.
    The solutions instead give as correct answers C and D because every class is supposed to be in its own file.
    Is this a general rule?
    When I find a question like this, how the code is supposed to be organised? Every class in its own file?

    Thank you!

    Welcome to the Ranch

    In this case, because there are several package delcarations, you have to assume the three classes are in different files. Also, all three classes are public so they must be in different files.
