1. package pkgA; 
2. public class Foo { 
3.    int a = 5; 
4.    protected int b = 6; 
5.    public int c = 7; 
6. } //from  w  w  w .  j  ava  2  s  .  co  m


3. package pkgB; 
4. import pkgA.*; 
5. public class Baz { 
6.   public static void main(String[] args) { 
7.     Foo f = new Foo(); 
8.     System.out.print(" " + f.a); 
9.     System.out.print(" " + f.b); 
10.     System.out.println(" " + f.c); 
11.   } 
12. }

What is the result?

Choose all that apply.

  • A. 5 6 7
  • B. 5 followed by an exception
  • C. Compilation fails with an error on line 7
  • D. Compilation fails with an error on line 8
  • E. Compilation fails with an error on line 9
  • F. Compilation fails with an error on line 10 


D and E are correct.

Note

Variable a has default access, so it cannot be accessed from outside the package.

Variable b has protected access in pkgA.

A, B, C, and F are incorrect based on the above information.
