Netbeans and Arguments (n00bish question)

[shadywatcher212]

Ok so this is a really n00bish question but i cant seem to find an answer for this.

Here is my source code:

Code:

class NewRoot {
    public static void main(String[] args){
        int number = 100;
        if (args.length > 0) {
            number = Integer.parseInt(args[0]);
        }
        System.out.println("The square root of "
                + number
                + " is "
                + Math.sqrt(number));
    }
}

I went to Run>Set Project Configuration>Customize and changed the argument to 169. I ran the file and it gives me the output of

Code:

The square root of 100 is 10.0

My question is why is it not taking the argument of 169 instead of evaluating 100? I checked the length of the argument and its 3. Any help would be appreaciated. Dont be to harsh im still begining Java.
