Question

JAVA Program ASAP

Modify this program below so it is a Filesorting.java program so it passes all the test cases when I upload it to Hypergrade. I have provided the failed test cases a screenshot. 

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
public class Main {
    public static void main(String[] args) {
        try {
            BufferedReader reader = new BufferedReader(new FileReader(getFileName()));
            String line;
            while ((line = reader.readLine()) != null) {
                processAndPrintSortedLine(line);
            }
            reader.close();
        } catch (IOException e) {
            System.out.println("Error reading the file: " + e.getMessage());
        }
    }
    private static String getFileName() {
        String fileName;
        java.util.Scanner scanner = new java.util.Scanner(System.in);
        do {
            System.out.println("Please enter the file name or type QUIT to exit:");
            fileName = scanner.nextLine();
            if (fileName.equalsIgnoreCase("QUIT")) {
                System.exit(0);
            }
            if (!fileExists(fileName)) {
                System.out.println("File " + fileName + " is not found. Please re-enter the file name.");
            }
        } while (!fileExists(fileName));
        return fileName;
    }
    private static boolean fileExists(String fileName) {
        try (BufferedReader reader = new BufferedReader(new FileReader(fileName))) {
            return true;
        } catch (IOException e) {
            return false;
        }
    }

    private static void processAndPrintSortedLine(String line) {
        String[] tokens = line.split(",");
        ArrayList<Integer> numbers = new ArrayList<>();

        for (String token : tokens) {
            numbers.add(Integer.parseInt(token));
        }

        // Use any sorting method from Sort.java
        // For example: Sort.insertionSort(numbers.toArray(new Integer[0]));
        // Arrays.sort(numbers.toArray(new Integer[0]));

        Arrays.sort(numbers.toArray(new Integer[0])); // Using insertion sort for demonstration

        // Convert ArrayList<Integer> to CharSequence[]
        CharSequence[] charSequences = new CharSequence[numbers.size()];
        for (int i = 0; i < numbers.size(); i++) {
            charSequences[i] = numbers.get(i).toString();
        }

        // Print the sorted numbers on the console
        System.out.println(String.join(",", charSequences));
    }
}
