[Pankaj Patel]

Hello 2 All.

Which of the follw are true statements.
1) A nested class is any class that is declared within the body of another class or interface.
2) A nested class can not be declared within the body of an interface declaration.
3) A top level class is a class which is not a nested class.
4) An inner class is a nested class that is not static.
5) A nested class can not be declared static.
6) A named class is any class that is not anonymous.
7) None of the above.


According to me 2,3,6 are correct. Am i right or wrong? Can anybody please justify.
Thanks.

1) A nested class is any class that is declared within the body of another class or interface.
2) A nested class can not be declared within the body of an interface declaration.
3) A top level class is a class which is not a nested class.
4) An inner class is a nested class that is not static.
5) A nested class can not be declared static.
6) A named class is any class that is not anonymous.
7) None of the above.

Options 1,3,4,6 are correct
1. A class can be declared inside an interface and will execute successfully.
4. Nested classes are classified as -
a. Static member class, and
b. Inner class (that includes - Non-static member class, Local class and anonymous class).

I hope this clarifies your doubts.

Yes. I am hanging between nested class and inner class.

Telling in detail :
-> A inner class is a class defined in a class of interface.
-> A class can be called as nested class if it is static inner class.
So both inner class and nested class is different word. Am i right?

i just finished reviewing K&B chapter 8,
from my understanding inner class simply means a non-static class implemented in a class;
nested class , has to be static, not really a "class", but just another static member of a class; it doesnt have the relationship with the outer class, it cant use other members of the class.

i could be wrong, open to discuss
