java.util.NoSuchElementException：從文件中讀取單詞

Question

這個簡單的Java程序怎么了？

我正在嘗試從文件中讀取單詞並得到以下異常：

complication
dilemma
lavender
issue
happy
weird
Exception in thread "main" java.util.NoSuchElementException
    at java.util.Scanner.throwFor(Scanner.java:907)
    at java.util.Scanner.next(Scanner.java:1416)
    at com.recrawl.util.ReadWordsTextfile.readWordsFromTextFile(ReadWordsTextfile.java:32)
    at com.recrawl.util.ReadWordsTextfile.main(ReadWordsTextfile.java:13)

如您所見，我得到了一些提示，但是我也得到了一個例外。 我正在使用以下代碼：

public static void main(String[] args) {
    String path = "Word_and_phrases";
    ReadWordsTextfile r = new ReadWordsTextfile();
    r.readWordsFromTextFile(path);  
}

public ArrayList<String> readWordsFromTextFile(String path) {
    ArrayList<String> resultList = new ArrayList<String>();

    FileInputStream fileIn = null;
    try {
        fileIn = new FileInputStream(path);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    Scanner scan = new Scanner(fileIn);
    while(scan.hasNextLine()) {
        String word = scan.next();
        word = word.replace(",", "");
        System.out.println(word);
        resultList.add(word);
    }
    scan.close();
    System.out.println(resultList.toString());
    return resultList;
}

非常感謝您的回答！

更新

txt文件的內容如下所示：

complication, dilemma, lavender, issue, happy, weird

第32行指出：

    String word = scan.next();

Answer 1

采用 ：

while(scan.hasNext())

代替：

while(scan.hasNextLine())

hasNext實現與next()而hasNextLine實現與nextLine()
