inner class in an Interface declaration

[Doug Tillman]

Can a nested class be declared in an Interface?
Question 15
Which of the follow are true statements.
a. A nested class is any class that is declared within the body of another class or interface.
b. A nested class can not be declared within the body of an interface declaration.
c. An inner class is a nested class that is not static.
d. A nested class can not be declared static.
e. A named class is any class that is not anonymous
The answers provided were a,c, & e - seems like the question is saying that b is 'true' since it is posed in a 'can not' formulation.
I can't create an example that compiles to prove that b should be true - any clarification most appreciated.
Thanks,
Doug

hi doug. I think you can. see code below:

public class tc {
    public static void main(String[] args) {
        System.out.println(faceinter.interfaceClass.message);
    }
}
interface faceinter{
    class interfaceClass{
        static String message = "hello world";
    }
}

In the example above, since the nested class is enclosed within an interface, it becomes implicitly public and static.

Hi doug,
A nested class can be declared within the body of an interface declaration. Here is a code snippet that I tried and compiles fine. Here class 'i' can be called an inner class because it is declared in an interface and I tried out class 'in' just for kicks:
public interface intCar
{
void drive();
class i
{
class in
{
void m()
{
System.out.println("m");
}
}
void m()
{
System.out.println("m");
}
}
}
ps: answers a and b negate each other so if a is true b has to be false
