导入要使用扫描仪读取的文本文件

Question

 private void readWords() throws IOException {
    initialCt = readFrom("C:\\Curses1.txt", initialWords);
    midCt     = readFrom("C:\\Curses2.txt", middleWords);
    endCt     = readFrom("C:\\Curses3.txt", endingWords);
  } // readWords()

  // Pre: fileName is the name of an input file. Tokens (items) in the
  // file are strings separated by whitespace.
  // Pre: wordList has been allocated and is large enough to hold all
  // the tokens in the input file.
  // Post: wordList contains all the tokens in the input file, one token
  // per string.


  private int readFrom(String fileName, String[] wordList) throws IOException {

     int count= 0;  

     FileInputStream fstream = new FileInputStream(fileName);
     Scanner scan2 = new Scanner (fstream);

     while (scan2.hasNext()){

         initialWords[count] =scan2.nextLine();
         middleWords[count] = scan2.nextLine();
         endingWords [count] = scan2.nextLine();

         String words = scan2.next();
         ++count;
      }

     return count;
  } // readFrom()

    Exception in thread "main" java.util.NoSuchElementException

我正在尝试读取三个不同的文本文件，并将它们的值存储在三个不同的数组中，但java无法找到该文件。这只是类的一部分，但这是发生错误的地方。任何帮助将不胜感激！

Answer 1

我相信它正在发生，因为String words = scan2.next(); 如果文件没有第4行，则抛出此异常。这是我能想到的唯一可行方式。如果有第4行，请检查文件。
