All,

The question no 1 is not clear in the chapter 10. It doesn't tell the class files are in different pacakages and If I assume the packagge is same my answer is different from the one given in book.

Do we get this type of questions in exam?? Or I have missed to read the question properly.

Thanks


Thanks,

Hi Anurag,

So, the question is:




Which statements are true? (Choose all that apply.)
A. The output is 0.
B. The output is 5.
C. The output is 6.
D. Compilation fails.
E. The code compiles if line 1 is removed.
F. The code compiles if line 2 is changed to read
Useful uuu = new Useful();


Answer:
3 D is correct. The increment() method must be marked public to be accessed outside of
the package. If increment() was public, C, E, and F would be correct.





I find, this pretty clear.. Note that there's a mention "in different files" and there's no package statement in the second class.. So it belongs to the default package.. not to the xcom package..

Regards,
Vishwa
