最近项目中用到要用周为单位统计数据,于是需要获得某时间段内的周的时间集合(开始时间和结束时间)
/**
* 获取某时间段内所有周的列表(开始时间,结束时间)
* @param startDate
* @param endDate
* @return
*/
public static List<String[]> getWeekList(Date startDate,Date endDate){
List<String[]> weekList = new ArrayList<>();
//转换成joda-time的对象
DateTime firstDay = new DateTime(startDate).dayOfWeek().withMinimumValue();
DateTime lastDay = new DateTime(endDate).dayOfWeek().withMaximumValue();
//计算两日期间的区间天数
Period p = new Period(firstDay, lastDay, PeriodType.days());
int days = p.getDays();
if (days > 0){
int weekLength = 7;
for(int i=0;i<days;i=i+weekLength){
String monDay = firstDay.plusDays(i).toString("yyyy-MM-dd");
String sunDay = firstDay.plusDays(i+6).toString("yyyy-MM-dd");
String [] week = {monDay,sunDay};
weekList.add(week);
}
}
return weekList;
}
