Access to Private Members of a Superclass

Question

What is the example of indirect access to private member of superclass from subclass?

A nested class has access to all the private members of its enclosing class—both fields and methods. Therefore, a public or protected nested class inherited by a subclass has indirect access to all of the private members of the superclass.

Answer 1

In the quote, we talk about "nested" class

here is an example of how an inner class can access private fields of the outer class.

class OuterClass {
private int x = 7;

public void makeInner(){
    InnerClass in = new InnerClass();
    in.seeOuter();
}
class InnerClass {
    public void seeOuter() {
        System.out.println("Outer x is " + x);
    }
}
public static void main(String[] args) {
    OuterClass.InnerClass inner = new OuterClass().new InnerClass();
    inner.seeOuter();
}

}

Finally, if you extend a class with the InnerClass, they will also access the private fields of the OuterClass if your InnerClass is public or protected
