我正在尝试制作一个游戏组喜欢的纸牌游戏的简单版本，以使我们的肢体残疾朋友可以参加游戏之夜。但是，当我尝试通过文本文件将卡数据值添加到ArrayList时，我在catch块中遇到java.util.NoSuchElementException的问题。
我试图打印值作为在Card类的cardToString（）方法中定义的字符串。当前代码将打印捕获的异常，然后在cardToString（）方法中显示默认情况，并在随机的Card实例中发生各种错误。第一个项目的名称应为“ Gradydon Creed”，最后一个输出的名称应为“ Power Absorption”
任何帮助将不胜感激！
这是我的主要方法类：
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();
}
我的甲板课程：
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();
}
}

答案 0 :(得分：0)
看来，您的MunchkinIDSheet.txt文件中的错误。看第二行：
1 1 1 1 1 1 1 10 0
只有9个元素，应该是10个，因为在while循环中，您使用10个元素进行迭代。我认为第八个元素10应该分别为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();
...
}
== EDIT ==
您所有的72条结果将是：
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
因为让我们在Card类中看到一些函数：
public static String getStackAsString() {
switch (stack) {
case DOOR:
return "Door";
case TREASURE:
return "Treasure";
default:
return "Unknown Stack";
}
}
有一种情况，您可以使用stack属性，并进行检查，但是将其初始化一次，则应将该属性传递给函数，例如：
public static String getStackAsString(String stack) {
...
}
因此，关于异常以及该异常的问题，因为第二行中有9个元素而不是10个元素。您需要重新查看代码和逻辑，以实现所需的结果。这是另一个问题。
