Calendar获取当前季度、月、周的开始时间结束时间

java在很多场合下会根据当前时间计算本季度的开始时间结束时间、当前月份的开始时间结束时间、当前周的开始时间以及结束时间。我这里整理下一个时间加工类，作为工具类记录下。

一、获取计算相关时间的方法如下：(如果有错误请指出，感谢！)

public class TimeUtils {

    /**
     * 初始化时间盒子
     * @return timeBox
     */
    public static TimeBox initTimeBox() throws ParseException {
        TimeBox timeBox = new TimeBox();
        Date currentDate = new Date();
        timeBox.setCurrentDate(currentDate);
        Date lastDate = getLastDate(currentDate);
        timeBox.setLastDate(lastDate);

        timeBox.setThisWeekStartDate(getCurrentWeekDateBegin(lastDate));
        timeBox.setThisWeekEndDate(getCurrentWeekDateEnd(lastDate));

        timeBox.setThisMonthStartDate(getCurrentMonthDateBegin(lastDate));
        timeBox.setThisMonthEndDate(getCurrentMonthDateEnd(lastDate));

        timeBox.setLastWeekStartDate(getLastWeekDateBegin(lastDate));
        timeBox.setLastWeekEndDate(getLastWeekDateEnd(lastDate));

        timeBox.setLastMonthStartDate(getLastMonthDateBegin(lastDate));
        timeBox.setLastMonthEndDate(getLastMonthDateEnd(lastDate));

        timeBox.setThisQuarterStartDate(getCurrentQuarterDateBegin(lastDate));
        timeBox.setThisQuarterEndDate(getCurrentQuarterDateEnd(lastDate));

        timeBox.setThisSundayDate(getCurrentWeekNumberDay(lastDate,0));
        timeBox.setLastSundayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,0)));

        timeBox.setThisMondayDate(getCurrentWeekNumberDay(lastDate,1));
        timeBox.setLastMondayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,1)));

        timeBox.setThisTuesdayDate(getCurrentWeekNumberDay(lastDate,2));
        timeBox.setLastTuesdayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,2)));

        timeBox.setThisWednesdayDate(getCurrentWeekNumberDay(lastDate,3));
        timeBox.setLastWednesdayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,3)));

        timeBox.setThisThursdayDate(getCurrentWeekNumberDay(lastDate,4));
        timeBox.setLastThursdayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,4)));

        timeBox.setThisFridayDate(getCurrentWeekNumberDay(lastDate,5));
        timeBox.setLastFridayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,5)));

        timeBox.setThisSaturdayDate(getCurrentWeekNumberDay(lastDate,6));
        timeBox.setLastSaturdayDate(getLastWeekDate(getCurrentWeekNumberDay(lastDate,6)));

        //确认当前周几，获取本周的所有日期


        timeBox.setStartDate(getEarliestDate(getLastMonthDateBegin(lastDate),getCurrentQuarterDateBegin(lastDate)));
        timeBox.setEndDate(getCurrentQuarterDateEnd(lastDate));



        return timeBox;
    }

    public static Date getEarliestDate(Date lastMonthStartDate, Date thisQuarterDateBegin) throws ParseException {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
        Date date = lastMonthStartDate;

二、TimeBox类

@Data
public class TimeBox {

    Date currentDate;
    Date lastDate;

    Date thisQuarterStartDate;
    Date thisQuarterEndDate;

    Date thisMonthStartDate;
    Date thisMonthEndDate;

    Date lastMonthStartDate;
    Date lastMonthEndDate;

    Date thisWeekStartDate;
    Date thisWeekEndDate;

    Date lastWeekStartDate;
    Date lastWeekEndDate;

    Date thisSundayDate;
    Date lastSundayDate;

    Date thisMondayDate;
    Date lastMondayDate;

    Date thisTuesdayDate;
    Date lastTuesdayDate;

    Date thisWednesdayDate;
    Date lastWednesdayDate;

    Date thisThursdayDate;
    Date lastThursdayDate;

    Date thisFridayDate;
    Date lastFridayDate;

    Date thisSaturdayDate;
    Date lastSaturdayDate;

    Date startDate;
    Date endDate;



    @Override
    public String toString() {
        return "TimeBox{" +

                '}';
    }
}

三、调用

System.out.println(TimeUtils.initTimeBox().myToString())
