Thank you for the replies you all. At first I tried the java tutorials provided by oracle but I found their website confusing to navigate. I borrowed this book called Introduction to Java Programming from a friend of mine and I've found it really helpful. I've been constantly working the examples and exercises and think I'm getting the hang of it, though I'm only finishing chapter three so I still have a long way to go.
Anyway I just wanted to say thanks for the replies.
One of the biggest things I suggest for you to do is pace yourself. Don't try to learn it all in a week, its not going to happen! I've been coding for only around two years now and I still am learning new things everyday, and I constantly still have to Google things or look them up in books. Its not that I'm a bad programmer, its just I haven't been doing it for long! When I was learning, however, I made a lot of console games. I'd start one, and then scrap it a day later because it frustrated me. Don't worry if you seem like you can't finish any projects you start, I still barely do!
Just work at it everyday, but remember to code things that you
enjoy. Don't just copy the book examples, make your own programs. I promise its one of the best ways to learn!
