我正在尝试让用户在ArrayList中输入数字。如果用户输入0，则对这些数字求和并求平均值

import java.util.ArrayList;
import java.util.Scanner;

public class ArrayListSumAndAverage {
    public static void main(String[] args) {
        ArrayList<Integer> numbers = new ArrayList<>();
        Scanner scanner = new Scanner(System.in);

        System.out.println("请输入数字（输入0结束输入）：");

        int input;
        do {
            input = scanner.nextInt();
            numbers.add(input);
        } while (input != 0);

        // 计算总和
        int sum = 0;
        for (int number : numbers) {
            sum += number;
        }

        // 计算平均值
        double average = (double) sum / numbers.size();

        System.out.println("数字总和为：" + sum);
        System.out.println("数字平均值为：" + average);
    }
}
