About Question enthuware.ocpjp.v7.2.1480 :

Is it right to say that class Inner cannot be accessed outside of the inner() method? I tried it out I can't seem to access it from main.

Thanks.

[admin]

Yes, that is correct.

Why I am seeing only answer number 1 as the correct?
Which is the other one?
Thanks in advance.

All Static Variables
All Final Automatic Variables.

There is a problem with the explanation code -- I don't think it changes the point being made but still, it should compile:

Code: Select all

public static void main( String[] args ) { TestClass.inner(); }

The code given in the explanation compiles fine. I just tried it.
HTH,

Hi,

all final automatic variables OK but only the ones within the static enclosing method. (not exactly all) just pointing out.

Hi,
"Which variables of the encapsulating class"

and in the answer "only si and fai are accessible in class Inner."

Both the answer and explanation given are inconsistent with the wording used in the question. A local (automatic) variable is NOT a variable of the encapsulating class.
Variable fai is NOT a variable of the encapsulating class TestClass. It's a variable of the method inside which Inner is defined.

There are class level (static and non-static) variables, and there are local variables. So the wording of the question and/or answer needs to be revised.

[admin]

The problem statement has now been updated to "Which variables declared in the encapsulating class or in the method..."

Hope that makes it clearer. Thank you for your feedback!
