consider the following code:

so here we have a subclass access a superclass instance, which are both in the "root" package world,
if i get rid of public at line 1, the compiler complaints.
is it because of subpackage is not considered as same package, or something else is wrong in the code?

just one more thing,
if i use
import world.moon;
in the world class,
why does it not work?

Hi Adam,

There's no such thing as a subpackage in Java. For all intents and purposes, "world" and "world.moon" are completely different packages. This is a bit non-intuitive because the .class files are stored hierarchically in the file system... but they don't in fact share a "subpackage" relationship in Java.

I agree. Here's the link:

It's not a secret anymore!
