扫描仪在输入时抛出 java.util.NoSuchElementException

Question

下面的这段代码抛出NoSuchElementException了函数aVeryBigSum。PS：这是hackerrank的任务，所以我只能修改函数中的代码：aVeryBigSum。

此函数接受以下输入：n要添加的数组中的元素数，以及数组的元素。

import java.io.*;

import java.math.*;

import java.security.*;

import java.text.*;

import java.util.*;

import java.util.concurrent.*;

import java.util.regex.*;

public class Solution {

    // Complete the aVeryBigSum function below.

    static long aVeryBigSum(long[] ar) {

        int n, sum = 0;

        Scanner read = new Scanner(System.in);

        n = read.nextInt();

        for(int i = 0; i < n; i++)

            sum += read.nextLong();

        return sum;

    }

    private static final Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) throws IOException {

        BufferedWriter bufferedWriter

                = new BufferedWriter(new FileWriter(System.getenv("OUTPUT_PATH")));

        int arCount = scanner.nextInt();

        scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");

        long[] ar = new long[arCount];

        String[] arItems = scanner.nextLine().split(" ");

        scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");

        for (int i = 0; i < arCount; i++) {

            long arItem = Long.parseLong(arItems[i]);

            ar[i] = arItem;

        }

        long result = aVeryBigSum(ar);

        bufferedWriter.write(String.valueOf(result));

        bufferedWriter.newLine();

        bufferedWriter.close();

        scanner.close();

    }

}

输出：
