如何根据 ArrayList 中的时间表一次打印一行?

How to printout a single line at time according to a schedule from an ArrayList?

我正在尝试创建一种一次打印一行的方法,中间有两分钟的延迟。我怎么做?。

这部分代码读取一个文本文件 (questionsFile) 并创建一个 ArrayList:

public Broadcaster(Socket connection) throws IOException {

    read = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    write = new PrintStream(connection.getOutputStream());  

    List<String> questionsList = new ArrayList<>();
    try (Stream<String> questionsStream = Files.lines(Paths.get(questionsFile))) {
        questionsList = questionsStream
                .parallel()
                .collect(Collectors.toList());

    } catch (IOException w) {
        w.printStackTrace();
    }

下面有一个计时器,但出于某种原因,我无法让它工作。整个 ArrayList 被打印出来,没有任何延迟。我的意图是使用 printStream 但出于测试目的,文本当前已打印到控制台。如何重写代码使其一次打印一行?

    List<String> finalQuestionsList = questionsList; 
    timer.schedule(task(() -> finalQuestionsList.forEach(System.out::println))
            , 120, TimeUnit.SECONDS.toMillis(1));
}

private TimerTask task(Runnable task) {
    return new TimerTask() {
        @Override
        public void run() {
            task.run();

简单的解决方案是:

for (String question : questionsList) {
    timer.schedule(task(() -> System.out.println(question)), 0);
    try {
        sleep(2000);
    } catch (Exception ignored) {}
}
