Calculate average in java

Question

EDIT: Ive written code for the average, but i dont know how to make it so that it also uses ints from my args.length rather than the array

I need to

Answer 1

If you're trying to get the integers from the command line args, you'll need something like this:

public static void main(String[] args) {
    int[] nums = new int[args.length];
    for(int i = 0; i < args.length; i++) {
        try {
            nums[i] = Integer.parseInt(args[i]);
        }
        catch(NumberFormatException nfe) {
            System.err.println("Invalid argument");
        }
    }

    // averaging code here
}

As for the actual averaging code, others have suggested how you can tweak that (so I won't repeat what they've said).

Edit: actually it's probably better to just put it inside the above loop and not use the nums array at all
