JAVA Protected variable not allowed to be access though an object in child class of different package

Question

Given two files:

package pkgA;
public class Foo {
int a = 5;
protected int b = 6;
}

---

1  package pkgB;
2  import pkgA.*;
3  public class Fiz extends Foo {
4     public static void main(String[] args) {
5        Foo f = new Foo();
6        System.out.print(" " + f.a);
7        System.out.print(" " + f.b);
8        System.out.print(" " + new Fiz().a);
9        System.out.println(" " + new Fiz().b);
10    }
11  }

What is the result? (Choose all that apply.)

A. 5 6 5 6
B. 5 6 followed by an exception
C. Compilation fails with an error on line 6
D. Compilation fails with an error on line 7
E. Compilation fails with an error on line 8
F. Compilation fails with an error on line 9

Ref: SCJP 1.6 Kathy_Sierra: As per Book Answer is C, D, E

Why NOT 'F'? can anybody please explain

Answer 1

Counting them down I assume that line 9 is supposed to be this line:

System.out.println(" " + new Fiz().b);

Protected variables are accessible to subclasses. Fiz is a subclass of Foo so it can access b. It can do so in a static context.
