验证多个时间段是否交叉

 

如下图：

代码如下：

public void checkTime(List<Available> list) {
    SimpleDateFormat sdf = new SimpleDateFormat(QuickCardConstant.DATE_FMT_HM);
    if (CollectionUtils.isNotEmpty(list)) {
      for (int i = 0; i < list.size(); i++) {
        Date dateBN;
        try {
          dateBN = sdf.parse(list.get(i).getBeginTime());
          Date dateEN = sdf.parse(list.get(i).getEndTime());
          for (int j = i + 1; j < list.size(); j++) {
            Date dateBN1 = sdf.parse(list.get(j).getBeginTime());
            Date dateEN1 = sdf.parse(list.get(j).getEndTime());
            if ((dateBN1.compareTo(dateBN) < 0 && dateBN.compareTo(dateEN1) < 0)
                || (dateBN1.compareTo(dateEN) < 0 && dateEN.compareTo(dateEN1) < 0)
                || (dateBN.compareTo(dateBN1) < 0 && dateBN1.compareTo(dateEN) < 0)
                || dateEN1.compareTo(dateBN) == 0 || dateBN1.compareTo(dateEN) == 0
                || dateEN1.compareTo(dateEN) == 0 || dateBN1.compareTo(dateBN) == 0) {
              throw new QuickCardException(ErrorCodeConstant.VALIDATA_AVAILABLE_TIME_CANNOT_CROSS);
            }
          }
        } catch (ParseException e) {
          logger.error("time handle error");
        }

      }
    }
  }

 

List<Available> list：是传进来的时间参数列表
