Why does my Java Zork Clone not loop correctly?
I'm making a Zork clone, and whenever it loops, an error comes up in Eclipse:

    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();
			}
		}
	}
    }
