Consider the following classes:

Consider the following classes:

package pkg1;
public class A {
    protected int num = 42;
}

package pkg2;
import pkg1.A;
public class B extends A {
    public int getNum() {
        return num;
    }
}

package pkg2;
public class C {
    public static void main(String[] args) {
        B b = new B();
        System.out.println(b.num);
    }
}

What will happen when compiling class C?
