Мой варинат тож работает, но не принимает валик

public class Solution {
    public static void main(String[] args) throws IOException {
        String fileName = args[0];
        StringBuilder builder = new StringBuilder();
        int count = 0;
        Scanner scanner = new Scanner(new FileReader(fileName));
        while(scanner.hasNext()) {
            String text = scanner.nextLine();


            String[] alphabetic = text.split("[^a-zA-Z]");


            for (int i = 0; i < alphabetic.length; i++) {
                builder.append(alphabetic[i]);
            }
        }
            count = builder.length();
            scanner.close();
            System.out.println(count);

    }
}

Программа работала слишком долго и была закрыта!

public class Solution {
    public static void main(String[] args) throws IOException {
        String fileName = args[0];
        StringBuilder builder = new StringBuilder();
        int count = 0;
        BufferedReader reader = new BufferedReader(new FileReader(fileName));
        while(reader.ready()) {
            String text = reader.readLine();


            String[] alphabetic = text.split("[^a-zA-Z]");


            for (int i = 0; i < alphabetic.length; i++) {
                builder.append(alphabetic[i]);
            }
        }
            count = builder.length();
            reader.close();
            System.out.println(count);

    }
}
