线程“主”中的异常java.util.NoSuchElementException首次试用

Question

我正在尝试启动此编码，但遇到以下错误消息：

  

线程“ main”中的异常java.util.NoSuchElementException在   java.util.Scanner.throwFor（Scanner.java:862）在   java.util.Scanner.next（Scanner.java:1485）在   java.util.Scanner.nextInt（Scanner.java:2117）在   java.util.Scanner.nextInt（Scanner.java:2076）在   Analysis.main（Analysis.java:17）

import java.util.Scanner;

public class Analysis
{
  public static void main(String[] args)
  {
    Scanner input = new Scanner(System.in);

    int passes = 0;
    int failures = 0;
    int studentCounter = 0;


    while (studentCounter <= 10)
    {
      System.out.print("Enter result (1 = pass, 2 = fail): ");
      int result = input.nextInt();

      if (result == 1)
        passes = passes + 1;
      else
        failures = failures + 1;

      studentCounter = studentCounter + 1;
    }

    System.out.printf("Passed: %d%nFailed: %d%n", passes, failures);

    if (passes > 8)
      System.out.println("Bonus");
  }
}

有人可以告诉我解决方法吗？ 谢谢。
