java - how do you input from the command line
 

i'm kinda perplexed, i've got a project for school where we're supposed to write a driver to allow piped input/output : for ex, driver < inputFile1 > outputFile but for a variety of input files. i can't figure out how to code this without specifically including the input file in the driver. can anyone help?

no worries, got it figured out.

The answer to the question is to use the System.in and System.out streams.

Please post the answers to your questions if you find out what they are; that way other people can benefit from your insight.

Well done on fixing it, though :)

I think zeviddalop meant take arguments when calling 'java' to exec the program. If that is the case, it is almost like C++:

class App
{
public static void main(String[] args)
{
//all command line arguments are stored in 'args'; just use it like a normal array
//(the exec name isn't given in [0], unlike C++)
}
}

If i were to read by lines, I would do:
