Ask yourself: What does "nested top-level inner" mean? :roll:

I think b,c, and d are correct:

public interface TopInterface{
public class InnerClass{
InnerClass(){
System.out.println("Hi");
}
public static void main(String r[]){
InnerClass in = new InnerClass();
}
}

}

Also

public class StaticInner{
public static void StaticMethod(){
class LocalClass{

}
}
}

Please let me know if this is wrong.

Thanks,
Fes

interface A{
class B{} //this is static!
}

because B is static, i think it is top-level inner class. if i am wrong, please correct me.
