Yes, they all are.

First you have `src/main/java` (compare `src/test/kotlin`), and then the package is encoded as nested directories, and Java has a convention of using the domain name as the root of your packages. So, if your company domain is "sun.com", all your packages start with "com.sun", and then you have more specifiers under that.

But all IDEs and github condense empty directories together, so it's not that bothersome.
