I don't think there's any difference between using javac and using an IDE. They're both tools that you configure and the press a button to run. What's the difference?

And the danger with saying 'you should understand it at the lower level' is anyone can challenge you if you understand the tools you use at a lower level, and at some point you won't, because nobody understands it all, and then they can point and laugh at you like you're pointing and laughing at others.
