Take a look at this page when you get a chance: http://www.oracle.com/technetwork/java/javase/documentation/codeconvtoc-136057.html
It will tell you some useful stuff about general programming conventions for java. It's good to get in the right habit early so you don't realize you're doing it wrong after you've done it for so long :P.
NewBoston is a good source too. Try to find the e-book for HeadFirst Java. That is an amazing book for learning the fundamental principles for Java. (from as little as primitive data types, to polymorphism, inheritance, networking, & concurrency ).
