Question

我想计算间隔直到某个日期。我测试了这段代码：

 String dateStop = "25/11/17 09:00:00";

        // Custom date format
        SimpleDateFormat format = new SimpleDateFormat("yy/MM/dd HH:mm:ss");

        LocalDateTime d1 = LocalDateTime.now();
        Date d2 = null;
        try
        {
            d2 = format.parse(dateStop);
        }
        catch (ParseException e)
        {
            e.printStackTrace();
        }

        // Get msec from each, and subtract.
        long diff = d2.getTime() - d1.getTime();

        long days = TimeUnit.MILLISECONDS.toDays(diff);
        long remainingHoursInMillis = diff - TimeUnit.DAYS.toMillis(days);
        long hours = TimeUnit.MILLISECONDS.toHours(remainingHoursInMillis);
        long remainingMinutesInMillis = remainingHoursInMillis - TimeUnit.HOURS.toMillis(hours);
        long minutes = TimeUnit.MILLISECONDS.toMinutes(remainingMinutesInMillis);
        long remainingSecondsInMillis = remainingMinutesInMillis - TimeUnit.MINUTES.toMillis(minutes);
        long seconds = TimeUnit.MILLISECONDS.toSeconds(remainingSecondsInMillis);

        System.out.println("Days: " + days + ", hours: " + hours + ", minutes: " + minutes + ", seconds: " + seconds);

但我如何获得当前日期并计算时差？我在这里得到例外：location：类型为LocalDateTime的变量d1

我如何解决这个问题？

Answer 1

getTime()没有LocalDateTime。请使用Date的{{1}}类代替或转换为它：

d1

计算日期范围直到将来的日期
