I agree with jwenting. If you don't understand how java is compiling your programs, nor how to compile without a program to do it for you...how do you expect to be a great java developer?
Not that Im great lol...that's ridiculous. I suck ass at java right now. But I still believe that the fundamentals are important, even if it all it does is help you get better at finding information online.
Remember it's the journey that counts not the end results.
