为什么我的Java Zork克隆不能正确循环？

我正在制作Zork克隆，每当它循环时，Eclipse中就会出现一个错误：

import java.util.Scanner;
public class Level1 {
public static void main(String[] args) {
    int x;  
    for(x=1; x<10; x++) {
        System.out.println ("Welcome to Sork - by Wyatt Lucas");
        System.out.println (" ");
        System.out.println ("Do you want to play?");
        Scanner first = new Scanner(System.in);
        @SuppressWarnings("unused")
        String firstInput;
        firstInput = first.nextLine();
        System.out.println("Well, it doesn't matter!");
        System.out.println("Use commands such as LOOK and GO NORTH \nto complete your adventure.");     
        System.out.println("");
        System.out.println("You are in a room.");
        Scanner second = new Scanner(System.in);
        String secondInput = second.nextLine();
        String look = "look";
        if(secondInput.equalsIgnoreCase(look)) {
            System.out.println("You look around and see a DOOR \nand a KEY on the floor.");
        }
        else {
            //don't use System.err.println. Just use System.out.println
            System.out.println("I do not understand that.");
            continue;
        }
        Scanner third = new Scanner(System.in);
        String thirdInput = third.nextLine();
        String pick_up_key = "pick up key";
        if(thirdInput.equalsIgnoreCase(pick_up_key)) {
            System.out.println("You picked up the KEY.");
        } else {
            System.out.println("I do not understand that.");
            continue;
        }
        Scanner fourth = new Scanner(System.in);
        String fourthInput = fourth.nextLine();
        String open_door = "open door";
        if(fourthInput.equalsIgnoreCase(open_door)) {
            System.out.println ("You open the door and are immediately \neaten by a grue!");
        } else {
            System.out.println("I do not understand that.");
        }

        first.close();
        second.close();
        third.close();
        fourth.close();
        try {
            Thread.sleep(1997);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
}

import java.util.Scanner；
公营一级{
公共静态void main（字符串[]args）{
int x；
对于（x=1；x运行代码到打开车门时

Exception in thread "main" java.util.NoSuchElementException: No line found
at java.util.Scanner.nextLine(Scanner.java:1516)
at Level1.main(Level1.java:12)

之所以发生这种情况，是因为您正在关闭System.in和所有
third.close（）
最后调用。只做一个扫描器，永远不要关闭它。
您还没有报告问题所在。为什么要构造一个新的扫描器来读取每一行？您可以重复使用同一个扫描器。我可以说，这种方法不会扩大到完成整个游戏？或者如果是这样，它将是一个无法维护的代码库？
