Encapsulation - Protected Attributes Should Be Visible To Child Classes

I found the following inheritance and encapsulation issue . Suppose you have a parent class with a non-static protected attribute.

package package1;
public class Parent{
protected int a = 10; // this is the non-static protected attribute in question
public static void main(String args[]){
// whatever logic
}// end Parent class
}// end main()

Now suppose you have a child class in another package and you have imported in the parent class.

package package2;
import package1.Parent;
public class Child extends Parent{
public static void main(String[] args){
Parent p = new Parent();
Child c = new Child();

System.out.println(p.a); //should print out 10 BUT DOES NOT
System.out.println(c.a); //should print out 10
}// end main()
}// end Child class

My observation is that p.a produces an error even though, to the best of my knowledge, it should not. I believe the statement "System.out.println(p.a);" should print out a 10.

Am I misunderstanding something about inheritance and encapsulation?
