所以我正在使用这个编译器站点处理我的代码：https : //www.tutorialspoint.com/compile_java_online.php

当我运行我的代码时，它出现了这个错误：

Exception in thread "main" java.util.NoSuchElementException
    at java.util.Scanner.throwFor(Scanner.java:862)
    at java.util.Scanner.next(Scanner.java:1485)
    at java.util.Scanner.nextInt(Scanner.java:2117)
    at java.util.Scanner.nextInt(Scanner.java:2076)
    at WorkingWithLoops.main(WorkingWithLoops.java:22)

这是我的代码：

import java.util.Scanner;

 public class WorkingWithLoops {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int negative = 0, positive = 0, sum = 0, value;
       
        System.out.print("Enter a value: ");
        value = input.nextInt();
       
        while (value != 0){
            if (value < 0){
                negative++;
            }
            else {
                positive++;
            }
           
            sum += value;
           
            System.out.print("\nEnter a value: ");
            value = input.nextInt(); …
