OK, they get passed to your main method when you write something like:

Code:

public static void main (String argv[]) {

The argv[] is an array of Strings made out of your commandline arguments. Here's an example:

Code:

// tmp.java
public class tmp {

    public static void main (String argv[]) {
        for(int i=0; i < argv.length; i++) {
            System.out.println("Got this on the commandline:" + argv[i]);
        }
    }

}

And the output:

Code:

charlie@charlie:~$ javac tmp.java
charlie@charlie:~$ java tmp hello world
Got this on the commandline:hello
Got this on the commandline:world
charlie@charlie:~$

HTH,
Charlie
