Else or ifn't

Wtf! what is this?

English is my second language. Today I learned Fedora is not just a Linux distro. It's also a name of a hat.
Guess the old logo made sense.

All the time while I'm programming I hate Java.... Don't hate me now :D I'm learning Java in high school. I very love very fast programming languages such as C and C++, so this is why I don't like Java, but there are some reasons why I like Java. I just started learning how to create own window. What the hack is this? This is so simple. I tried to create window in C/C++ with OpenGL, just blank window with color. Complicated..... But with java it's fairy tale.
You can add me now to Java familly, but remember I also love C++.

So here your are, Hello World Java FX app :D

Final goal:
Create window application similar scratch.

Me: I have admin rights
Windows: Looks legit
Me: can I delete this folder ?
Windows: Nope
