Here are 2 Ques. fom JExam about which i have doubt.

Which of the following statements are true regarding inner classes.
Possible Answers:
-------------------
Possible Answer 1:
Variables defined inside inner classes cannot be static.

Possible Answer 2:
Variables defined inside inner classes cannot be static unless the inner class itself is static.

Possible Answer 3:
Non-static inner classes (which are not defined in a method) have access to all class and instance variables, regardless of the access qualifier of those variables.
Possible Answer 4:
An inner class can actually be a subclass of the outer class

Possible Answer 5:
Inner classes can be declared as private. Top level, outer classes cannot.
Correct answer given is 2 whereas i think 1 is also correct as they
themselves has explained in 2.
The argument for a "case" statement must be a constant or a constant expression which can be evaluated at compile time.
Possible Answers:
-------------------
Possible Answer 1:
True

Possible Answer 2:
False

Correct Answer...
-----------------
Answer 1:
True
I think correct answer is false because constant or constant expression
should not be long float,double,boolean.They should have explicitly
mention it.
Please express your views.
Thankx.

question 1) i say answers 3, 4, and 5 are correct. As for answers 1 and 2, the fact is that non-static inner classes can have static members if those members are also final.
question 2) the fact that the argument for a case statement must be assignable to int does not make the statement that it must be a constant false.

Sorry for placing my Question wrong. Actually what I wanted to ask was if in Q1 choice 2 is correct than choice 1 is also true.Choice 3,4,5 are obviously true.Indeed they have given choices 2,3,4,5 as true.
Once again sorry for miscommunication.
Randall can you explain it with a example.
Thanks.
