Question

我试图在2分钟内读取字符串，但最后ListOfwords只获得第一个字。有什么建议吗？

 ArrayList<String> listOfWords = new ArrayList<String>();
 String word;

  try{
    System.out.println("Guess words: ");    
    Thread.sleep(time*1000*120);
    word = in.next();
    listOfWords.add(word);
    System.out.println("Out of time!!!!!!\n");
    } catch (InterruptedException e){
        e.printStackTrace();
    }

 System.out.println(listOfWords);

使用Timer来安排任务（即读取字符串），尝试使用以下代码：

    Timer timer = new Timer();
    timer.schedule(new TimerTask() {

        @Override
        public void run() {
            ArrayList<String> listOfWords = new ArrayList<String>();
            String word;
            System.out.println("Guess words: ");
            try {
                Thread.sleep(60000);
            } catch (InterruptedException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            }
            Scanner in = new Scanner(System.in);
            word = in.next();
            listOfWords.add(word);
            System.out.println(word);
            System.out.println("Out of time!!!!!!\n");
        }
    }, 0, time);
