How do I install the Oracle JDK 8?
You'll need to go to Oracle's JDK 8 Downloads page and sign in with an Oracle account before you can download the Linux x64 Compressed Archive.
It looks like Oracle has an install guide that may be able to help you get started.
I'm going to try and get this setup myself and try to spot any hiccups you may run into and I'll be sure to let you know what I find.
