java在很多場合下會根據當前時間計算本季度的開始時間結束時間、當前月份的開始時間結束時間、當前周的開始時間以及結束時間。我這裏整理下一個時間加工類，作爲工具類記錄下。
一、獲取計算相關時間的方法如下：(如果有錯誤請指出，感謝！)
public class TimeUtils {
/**

* @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)));
//確認當前周幾，獲取本週的所有日期
timeBox.setStartDate(getEarliestDate(getLastMonthDateBegin(lastDate),getCurrentQuarterDateBegin(lastDate)));

二、TimeBox類
@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{" +

}
public String myToString() {

'}';
}
}
三、調用
System.out.println(TimeUtils.initTimeBox().myToString())
