What is the output when the main() method is executed?

public class Parent {
    private void secret() {
        System.out.println("Parent secret");
    }
    public void reveal() {
        secret();
    }
}

public class Child extends Parent {
    private void secret() {
        System.out.println("Child secret");
    }
}
public class Main {
    public static void main(String[] args) {
        Parent p = new Child();
        p.reveal();
    }
}
