Command line arguments via (string[] args)

[Matt Moore]

Hi

I've been told that you can pass a text file to be inputted via the (String[] args) part of the main method.

eg.

java someprogram someinput.txt

Well thats what I'd like to do, how do I do it?

thanks,

Matt

if ( args.length > 0 )
    BufferedReader in = new BufferedReader(new FileReader(args[0]));

This assumes the file is in the same directory as someprogram, otherwise you have to specify the path.
