如何修復java.util.NoSuchElementException錯誤

Question

我正在嘗試制作游戲組喜歡的紙牌游戲的簡單版本，以使我們的肢體殘疾朋友可以參加游戲之夜。 但是，當我嘗試通過文本文件將卡數據值添加到ArrayList時，我在catch塊中遇到java.util.NoSuchElementException的問題。

我試圖將值打印為Card類的cardToString（）方法中定義的字符串。 當前代碼將打印捕獲的異常，然后在cardToString（）方法中顯示默認情況，並在隨機的Card實例中發生各種錯誤。 第一個項目的名稱應為“ Gradydon Creed”，最后一個輸出的名稱應為“ Power Absorption”

任何幫助將不勝感激！

這是我的主要方法類：

private static int stack, type, name, text, bad, level, treasure, pLevel, modifier, rank;

public static void main(String[] args) {  

    Deck deck = new Deck();

    try {
        Scanner inputStream = null;

        inputStream = new Scanner(new FileInputStream("MunchkinIDSheet.txt"));

        while(inputStream.hasNextLine()){
            stack = inputStream.nextInt();
            type = inputStream.nextInt();
            name = inputStream.nextInt();
            text = inputStream.nextInt();
            bad = inputStream.nextInt();
            level = inputStream.nextInt();
            treasure = inputStream.nextInt();
            pLevel = inputStream.nextInt();
            modifier = inputStream.nextInt();
            rank = inputStream.nextInt();

        deck.addCard(new Card(stack, type, name, text, bad, level, treasure, pLevel, modifier, rank));
        }

        inputStream.close();
    }
    catch (Exception e) {
        System.out.println(e);
    }

    deck.list();
}

我的甲板課程：

import java.util.ArrayList;

public class Deck {
private static ArrayList<Card> deck = new ArrayList<>();

public void addCard(Card n){
    deck.add(n);
}

public static void list(){
    for(int i = 0; i <= deck.size(); i++){
        System.out.println(i + " " + Card.cardToString(deck.get(i)));
        System.out.println();
    }
  }
}

Answer 1

看來，您MunchkinIDSheet.txt文件中的錯誤。 看第二行：

1 1 1 1 1 1 1 10 0

只有9個元素，應該是10個，因為在while循環中，您使用10個元素進行迭代。 我認為第八個元素10應該分別為1和0：

while(inputStream.hasNextLine()){
    stack = inputStream.nextInt();
    type = inputStream.nextInt();
    name = inputStream.nextInt();
    text = inputStream.nextInt();
    bad = inputStream.nextInt();
    level = inputStream.nextInt();
    treasure = inputStream.nextInt();
    pLevel = inputStream.nextInt();
    modifier = inputStream.nextInt();
    rank = inputStream.nextInt();
    ...
}

==編輯==

您所有的72個結果將是：

0 Stack: Door
Type: Power
Name: Power Absorption
Power: Rank 3
Text: You may discard a card to try to steal a Power carried by another player.  Roll the die; 4 or higher succeeds.  Otherwise, you get caught and lose a Level.
Bonus: 3

因為讓我們看一下Card類中的一些函數：

public static String getStackAsString() {
    switch (stack) {
    case DOOR:
        return "Door";
    case TREASURE:
        return "Treasure";
    default:
        return "Unknown Stack";
    }
}

有，您可以使用stack屬性，並對其進行檢查，但是將其初始化一次，則應將該屬性傳遞給函數，例如：

public static String getStackAsString(String stack) {
    ...
}

所以，關於異常以及這個異常的問題，因為第二行中有9個元素而不是10個元素。 您需要重新查看代碼和邏輯，以實現所需的結果。 這是另一個問題。
