Understanding java's protected modifier

Question

I have a class called A in package1 and another class called C in package2. Class C extends class A.

A has an instance variable which is declared like this:

<

Answer 1

 public void go(){
        //remember the import statement
        A a = new A();
        System.out.println(a.publicInt);
        System.out.println(a.protectedInt);

    }

When you are doing A a = new A(); and a.protectedInt you trying to access protected member of A which is illegal according to java standards

Instead you can do this.protectedInt directly.
