如何将文本文件拆分为两个不同的数组？

Question

I have this method which reads the file and converts it into an array. The text file looks something like this, but there can be any number of items on the text file:

Ball 200
Car 20000
Goat 200

etc.

I need to split each line with a \n delimiter and each word from the number with a \t delimiter, but I'm not sure the syntax to use to actually split it that way and add each one to a different array (ie ball goes into one array and 200 goes into another). I figured I could split each line inside of the method I have, but I was not sure how to implement it.

EDIT: This is for a class and I'm not actually allowed to use any other storage system in the program besides arrays. :')

public static String[] readFile(String fileName) {
    try {
        
        Scanner fileScanner = new Scanner(new File(fileName));
        //Gets the length of the text file. How many lines there are.
        int wordCount = 0;
        while(fileScanner.hasNextLine()) {
            fileScanner.nextLine();
            wordCount++;
        }
        if(wordCount <= 0) 
            return null;
        
        //Creates an array using the length from the previous code.
        String[] finArr = new String[wordCount];
        fileScanner = new Scanner(new File(fileName));
        for(int i = 0; i <  finArr.length; i++) {
            if(!fileScanner.hasNextLine())
                break;
            finArr[i] = fileScanner.nextLine();
        }
        return finArr;
            
    }
    catch(IOException e) {
        System.out.println(e);
    }
    catch(Exception e) {
        System.out.println(e);
    }
    return null;
}

public static void main(String[] args) {
    String data = "Ball 200\nCar 20000\nGoat 200";
    List<String> words = new ArrayList<>();
    List<Integer> numbers = new ArrayList<>();
    
    try (BufferedReader reader = new BufferedReader(new StringReader(data))) {
        String line = reader.readLine();
        while (line != null) {
            String[] tokens = line.split("\\s");
            words.add(tokens[0]);
            numbers.add(Integer.parseInt(tokens[1]));
            line = reader.readLine();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    System.out.println(words);
    System.out.println(numbers);
    //If you really need it as an array
    String[] arrWords = words.toArray(new String[]{});
    Integer[] arrNums = numbers.toArray(new Integer[]{});

    System.out.println(Arrays.toString(arrWords));
    System.out.println(Arrays.toString(arrNums));
}
