java.util.NoSuchElementException:从文件中读取单词

java.util.NoSuchElementException: Read words from a file

这个简单的 java 程序有什么问题?

我正在尝试从文件中读取单词并出现以下异常:

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)

正如你所看到的,我得到了这些词,但是我也得到了一个例外。我正在使用以下代码:

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;
}

非常感谢您的回答!

更新

txt 文件的内容如下所示:

complication, dilemma, lavender, issue, happy, weird

第 32 行是:

    String word = scan.next();

使用:

while(scan.hasNext())

而不是:

while(scan.hasNextLine())

hasNext 实现与 next() 一起工作,而 hasNextLine 实现与 nextLine()

一起工作
