如何从CSV文件中对Java中的2组数字求和？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class CSVSumCalculator {
    public static void main(String[] args) {
        String csvFile = "path/to/your/csv/file.csv";
        String line;
        String csvSplitBy = ",";

        int sum1 = 0;
        int sum2 = 0;

        try (BufferedReader br = new BufferedReader(new FileReader(csvFile))) {
            while ((line = br.readLine()) != null) {
                String[] numbers = line.split(csvSplitBy);
                if (numbers.length >= 2) {
                    sum1 += Integer.parseInt(numbers[0]);
                    sum2 += Integer.parseInt(numbers[1]);
                }
            }
            System.out.println("Sum of group 1: " + sum1);
            System.out.println("Sum of group 2: " + sum2);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
