扫描程序：线程“main”java.util.NoSuchElementException中的异常

Question

背景：我正在学习Java编程课程。

这是一个我想解决的简单问题：

“编写一个程序，提示用户输入分钟，并显示分钟的年数和天数。”

这是我到目前为止所写的：

import java.util.Scanner;


public class Main {

public static final int MINUTES_PER_YEAR = 525600;
public static final int MINUTES_PER_DAY = 1440;

public static void main(String[] args) {

    // CH2.7 SOLUTION

    // declare variables 
    int minutes;
    int years;
    int days;

    // create scanner object to prompt user for minutes
    Scanner input = new Scanner(System.in);
    System.out.println("Enter the number of minutes: ");
    minutes = input.nextInt();
    input.close();

    years = minutes / MINUTES_PER_YEAR;
    days = minutes % MINUTES_PER_DAY;

    System.out.println(minutes + " minutes is approximately " + years + " years and " + days + " days.");
    }
}

这是我在Codenvy基于云的IDE中收到的错误消息：

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 Main.main(Main.java:21)

任何指导都将不胜感激。
