static class A {
void process() throws Exception { throw new Exception(); }
}
static class B extends A {
void process() { System.out.println("B "); }
}
public static void main(String[] args) {
A a = new B();
a.process();
}

A. B
B. The code runs with no output.
C. An exception is thrown at runtime.
D. Compilation fails because of an error in line 15.
E. Compilation fails because of an error in line 18.
F. Compilation fails because of an error in line 19.


They have given the answer is F.But here static modifier is not allowed to a top level class.So the answer should be Compilation fails.Then F is wrong.Please clarify me.

Hello "Apple Java", welcome to JavaRanch.

First, you have to pay attention to two administrative things.

1. We have a naming policy on JavaRanch. Obviously fake names like "Apple Java" are not allowed here. Please read the naming policy carefully and change your display name by editing your profile.

2. When you copy a question from a mock exam, book or other source, we require that you quote your sources. So, please tell us where you copied this question from.
