I am trying to read several doubles from a file and save them in an array. The first number in the file is an integer, which should then determine the size of the array. This works. but when I try to read in the doubles afterwards, I get a false return and it skips the loop. what could be the reason for this?

Heres the method I use for reading the file

public static void readFile()
    {

        System.out.println("Filename (Has to be on Desktop): ");
        Scanner scan = new Scanner(System.in);
        String fileName = scan.nextLine();
        String filePath = searchFileOnDesktop(fileName + ".txt");

        try
        {
            File file = new File(filePath);
            Scanner reader = new Scanner(file);
            int arraySize = reader.nextInt();
            double[] data = new double[arraySize];
            //reader.next();
            while (reader.hasNextDouble())
            {
                int i = 0;
                data[i] = reader.nextDouble();
                System.out.println(data[i]);
                i++;
            }
            reader.close();
        }
        catch (FileNotFoundException e)
        {
            System.out.println("Datei konnte nicht geöffnet werden.");
            e.printStackTrace();
        }
    }

I have already tried to “reset” the reader with .next(). at least that’s what I read somewhere. I can’t read it in as an integer, string or whatever else there is
