Best way to learn Java with autism?

Odd question but I believe my autism is making it hard for me to learn Java. I've been trying for quite three years now, but like everything else it comes to a grinding halt. When I write code that I know I find it fun, but when I try to learn anything new any progress just stops. It's the same at school, sports, anything. I found tutorial videos to work well as I have extreme issues with reading comprehension and amazingly in 17 years of life no one else, including me, has noticed(I know I have it because most people don't have to re-read the same line/paragraph literally 3-4 times to retain shreds of information).

Some facts about me:
It's not internet autism, I was actually diagnosed with it by a doctor.
The form of it is Asphergers(Spelling?)
Currently 17 years old

EDIT: Also have a bandwidth cap so videos are off limits


Any help would be appreciated.
