I'm having trouble setting up and placing values into an array using a text file containing the floating point numbers 2.1 and 4.3 each number is separated by a space - below is the error I'm getting:

Exception in thread "main" java.util.NoSuchElementException

import java.util.*;
import java.io.*;

public class DoubleArray {

    public static void main(String[] args) throws FileNotFoundException {   

        Scanner in = new Scanner(new FileReader("mytestnumbers.txt"));

        double [] nums = new double[2];


            for (int counter=0; counter < 2; counter++) {
            int index = 0;
            index++;
            nums[index] = in.nextDouble();
            }
    }
}

Thanks, I'm sure this isn't a hard question to answer... I appreciate your time.
