如何在Java中检测日期是在本周还是下周内？

这部分取决于您所说的“本周”和“下周”的意思…但是使用Joda Time可以很容易地确定它是在“今天”还是“接下来的7天”：

LocalDate event = getDateFromSomewhere();LocalDate today = new LocalDate();LocalDate weekToday = today.plusWeeks(1);LocalDate fortnightToday = weekToday.plusWeeks(1);if (today.compareTo(event) <= 0 && event.compareTo(weekToday) < 0){    // It's within the next 7 days}else if (weekToday.compareTo(event) <= 0 && event.compareTo(fornightToday) < 0){    // It's next week}

编辑：要获取周日至周六，您可能需要：

LocalDate startOfWeek = new LocalDate().withDayOfWeek(DateTimeConstants.SUNDAY);

然后执行与上述相同的代码，但相对于startOfWeek。
