NoSuchElementException in Linux
Greetings all. I have a rather interesting problem with the Scanner class, and Google hasn't been able to help.
Some background: I just bought a new laptop for college and am dual-booting Linux and Vista (because it comes standard with Vista). On my old laptop I had XP, so I used that primarily for programming, but now that I have to have Vista I'm using mainly Ubuntu for coding.
I transferred over my files and tried to execute one of my programs. The particular section giving the error is supposed to read in a configuration file ("config.inf") and set the look and feel and other options based on what it finds; the part of config.inf it's looking for comes after a '#' character, so it reads through until it gets there, reads the next line, and acts on that line's contents. On XP it works perfectly; on Ubuntu the Scanner class doesn't seem to want to work. This:
returns a NoSuchElementException at the "temp=in.nextLine();" right after the while loop. I've tried to debug it and for some reason it thinks config.inf is empty; printing the value of temp has no effect because the while loop apparently never executes.
Scanner in=new Scanner(new File("config.inf")).useDelimiter("\r|\r\n|\n");
//do other stuff
My best guess was that the Windows line separator difference ("\r\n" instead of '\n') is the problem, so I set the Scanner to use both kinds of delimiters, but that didn't work. If that is the issue, and I just didn't fix it correctly, does anyone know how to fix that? If not, does anyone know what the problem actually is?
Thanks in advance for your assistance.
