I’m kind of new to visibility and want to really internilize these concepts.
I’ve learnt that “package-private”, the default visibility in Java, allows us to see fields from classes in the same package; and that protected, apart from implying package visibility,
also allows us, from class Child in otherPackage, get fields declared in Parent class in thisPackage,
as long as we are asking for them to an instance of class Child or a descendant.
