Wow, how discouraging, that only teaches him "If you can start, don't bother trying at all." Which is the most stupid thing I've heard.
Some people have different learning methods, perhaps he would learn better if someone were guiding him or teaching him, rather than a straightforward website that teaches you things.
(Cute profile pic, regardless)
I learned by reading documentation about whatever I was trying to learn... The fact that I'm a web developer lead me to the Mozilla docs (Mozilla is a browser engine which FireFox is based off, so you can trust the information).
https://developer.mozilla.org/en-US/For Java, I've been
super interested in Java, but you can consider reading the documentation (that's where I started, but I quit later on)
http://docs.oracle.com/javase/tutorial/(That's a tutorial they've written up)
But, like I mentioned above, perhaps reading or tutorials don't help you. Maybe you need a different method, as far as that goes, I cannot help.
