所以这是我的代码：

public static void getArmor(String treasure)

throws FileNotFoundException{

Random rand=new Random();

Scanner file=new Scanner(new File ("armor.txt"));

while(!file.next().equals(treasure)){

file.next(); //stack trace error here

}

int min=file.nextInt();

int max=file.nextInt();

int defense=min + (int)(Math.random() * ((max - min) + 1));

treasure=treasure.replace("_", " ");

System.out.println(treasure);

System.out.println("Defense: "+defense);

System.out.println("=====");

System.out.println();

}

public static void getTreasureClass(Monster monGet)

throws FileNotFoundException{

Random rand = new Random();

String tc=monGet.getTreasureClass();

while (tc.startsWith("tc:")){

Scanner scan=new Scanner(new File ("TreasureClassEx.txt"));

String eachLine=scan.nextLine();

while(!tc.equals(scan.next())){

eachLine=scan.nextLine();

}

for (int i=0;i<=rand.nextInt(3);i++){

tc=scan.next();

}

getArmor(tc); //stack trace error here

}

}

出于某种原因,我得到了一个没有这样的元素例外

我不知道为什么会这样.基本上我的程序正在搜索两个文本文件 – armor.txt和TreasureClassEx.txt. getTreasureClass从一个怪物接收一个宝藏类并搜索txt,直到它到达一个基础装甲物品(一个不以tc：开头的字符串).然后它在getArmor中搜索一个与其得到的基础护甲名称相匹配的护甲.宝藏班.任何意见,将不胜感激！谢谢！
