Here is my code :

```
public static double columnSum(String filename, int column) {
    double sum = 0;

    try {
        Scanner scan = new Scanner(new File(filename));
        while (scan.hasNextLine()) {
            String s = scan.nextLine();
            sum = sum + Double.parseDouble(s.split(",")[1]);
        }
    } catch (FileNotFoundException e) {
        System.out.println("Inout file " + filename + " does not exist");
    }
    return sum;
}

```

I would like to try and skip the first line of my text file in order to avoid the `NumberFormatException` error i'm getting but I don't know what to do to my code to do that.

this is an example of the file to read
