如何在只有一行扫描仪输入的情况下对int数组的所有元素求和

import java.util.Scanner;

public class ArraySum {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入一行整数，以逗号分隔：");
        String input = scanner.nextLine();

        String[] numbers = input.split(",");
        int[] array = new int[numbers.length];

        for (int i = 0; i < numbers.length; i++) {
            array[i] = Integer.parseInt(numbers[i]);
        }

        int sum = 0;
        for (int num : array) {
            sum += num;
        }

        System.out.println("数组元素的求和结果为：" + sum);
    }
}
