I’m pretty sure Java doesn’t have pointers, so writing a hello world application isn’t gonna fuck up nearly that hard.
The one thing he forgot though is that your source file is probably in the folder
com/companyname/net/classes/factory/factoryfactory/worker/lib/bin/refresh/jdk/model/ui/closebutton/press.java
And spread out among a bunch of other directories, and the java file is like…3 lines. But there are 10k files spread all around directories like this that are all 3 lines a piece with a class definition.
Thankfully, despite naming them like that, it doesn’t actually seem to have any real purpose. Apparently they just wanted to make sure that different companies making different libraries didn’t accidentally use the same name for their project…
