Access Protection

Question

Sir i was trying to check the access rights given in the complete reference. The book says that we can access the protected variables in a different package and within a subclass. But i was not able to access the protected variable from a different package though i extended the package. i was able to access the public variable. I am also attaching my code below.
//This is the code where i am importing the package and extending the class within the package.
import PackagePPP.*;
public class PPP extends inpack
public int i=10;
protected int j=20;
private int k=30;
int l=40;
public static void main(String args[])
     inpack p = new inpack();
     System.out.println("diff package diff class-->"+p.i);
     //System.out.println("diff package diff class-->"+p.j);
     //System.out.println("diff package diff class-->"+diff.k);
     //System.out.println("diff package diff class-->"+p.l);
//This is how i have created the package.
package PackagePPP;
public class inpack
     public int i=10;
     protected int j=20;
     private int k=30;
     int l=40;
}

Hi,
The book says that we can
access the protected variables in a different package
and within a subclass. That's wrong. You can access protected attributes of classes that are in the same package, or if you are subclassing.
