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

No need to instantiate Protection class inside Protection2 Class. You can directly call the protected variable without instantiating the Protection class. Because Protection2 class extends Protection class. So variable automatically inherited by subclass.

Try with below code:

public class Protection2 extends Protection{
Protection2()
{System.out.println("n_pro = " +n_pro);
}}
