Head First book "% javac"

Brand new to this Java game (although I've been an old-style programmer for 30 years) and I'm using the Head First book.

It keeps referring to command prompts % javac and similar.

What the heck is the % for?

what OS are you using? that '%' is really just your command line. on windows, it might actually be "C:\>". on Unix, it might look like "->", etc.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

It only refers to your command prompt. If you're on Windows, think of it as C:\>.

Thanks guys. I knew the code worked without the "%" - I just didn't realise that it meant "command prompt" - it actually looks like you're meant to type it.
I agree. Here's the link:
