Question 215

Examine the content of App.java:

Which is true?

The App.class file is stored within the p1 folder. The Test.class file is stored within the p2 sub-folder of p1.

The App class is accessible within the Test class without an import statement.

import p1.App; is used to access the App class within the Test class.

It is optional to have the package statement as the first line of class definitions.

Correct Answer: A

The App class file should be stored in the p1 directory because it belongs to the p1 package. Similarly, the Test class file belongs to the p1.p2 package, so it should be stored in a subdirectory p2 within the p1 directory. Thus, the correct assertion is that the App.class file is stored within the p1 folder, and the Test.class file is stored within the p2 sub-folder of p1.

Discussion

iSnoverOption: C

I really didn't understand the purpose of the question, the same question which of the alternatives is true, but the letters A, C and D are correct and I still tested it just in case. Answer B is the only one that is wrong because to use the app class inside Test you need to do the import because they are in different packages... Now if the question refers to which answer fits the context of the utterance, it would mark answer C. NOTE: Following this logic, for the sake of conscience, I would mark the one that has more to do with the context, because it would be "the most correct".

D is also wrong, in this context.
