Java DateUtils是Apache Commons Lang库中的一个工具类,可以用来进行日期计算。以下是使用Java DateUtils进行日期计算的一些示例代码:
Date startDate = new Date();
Date endDate = DateUtils.addDays(startDate, 7);
long daysDiff = DateUtils.getFragmentInDays(endDate, startDate);
System.out.println("Days difference between two dates: " + daysDiff);
Date currentDate = new Date();
Date futureDate = DateUtils.addDays(currentDate, 30);
System.out.println("Future date after adding 30 days: " + futureDate);
Date date1 = new Date();
Date date2 = new Date();
boolean isSameDay = DateUtils.isSameDay(date1, date2);
System.out.println("Are the two dates on the same day? " + isSameDay);
Date startDate = new Date();
Date endDate = DateUtils.addDays(startDate, 7);
List<Date> datesInRange = DateUtils.getDates(startDate, endDate);
for (Date date : datesInRange) {
System.out.println(date);
}
以上是使用Java DateUtils进行日期计算的一些示例,你可以根据具体的需求选择适合的方法来进行日期计算。
