BB && KS Practice Exams - Practice Exam 2, question 29 - wrong answer?

[Stoian Azarov]

The question is from the BB && KS Practice Exams book

29. Given that:
Exception is the superclass of IOException, and
IOException is the superclass of FileNotFoundException, and

import java.io.*;
class Physicist {
    void think() throws IOException { }
}

public class Feynman extends Physicist {
    public static void main(String[] args) {
        new Feynman().think();
    }
    // insert method here
}

Which of the following methods, inserted independently at line 11, compiles? (Choose all
that apply.)
A. void think() throws Exception { }
B. void think() throws FileNotFoundException { }
C. public void think() { }
D. protected void think() throws IOException { }
E. private void think() throws IOException { }
F. void think() { int x = 7/0; }

Answer (for Objective 1.4):
B, C, D, and F are correct. It’s legal for overridden methods to have less restrictive
access modifiers, to have fewer or narrower checked exceptions, and to have unchecked
exceptions. (Note: Of course, F would throw an exception at runtime.)

A is incorrect because Exception is broader. E is incorrect because private is more
restrictive.

________________________________________
I think there is something wrong with the answer
B does not compile because FileNotFoundException is not caught in the main method
D does not compile because IOException is not caught in the main method

Can someone confirm my supposition, or I am missing something?

You're right. For B & D, in order for the code to compile, the public static void main(String[] args) method must either claim to throw the checked exception or handle the checked exception.

Hi, you are right, I post same question few months ago, Bert Bates confirm an error in question.
