java季度时间获取工具类

1.获取当前季度 第一天或最后一天

/**
     * 获取季度 第一天或最后一天
     *
     * @param quarters 0本季度，1下季度，-1上季度 以此类推
     * @param isFirst  true获取开始时间 false获取结束时间
     * @return java.lang.String
     */
    public static ZonedDateTime getStartOrEndDayOfQuarter(long quarters, Boolean isFirst) {
        System.out.println(LocalDate.now());
        LocalDate resDate = LocalDate.now().plusMonths(quarters * 3);
        Month month = resDate.getMonth();
        Month firstMonthOfQuarter = month.firstMonthOfQuarter();
        Month endMonthOfQuarter = Month.of(firstMonthOfQuarter.getValue() + 2);
        if (isFirst) {
            resDate = LocalDate.of(resDate.getYear(), firstMonthOfQuarter, 1);
        } else {
            resDate = LocalDate.of(resDate.getYear(), endMonthOfQuarter, endMonthOfQuarter.length(resDate.isLeapYear()));
        }
        return resDate.atStartOfDay(((ZoneId.systemDefault())));
    }

2.获取传入时间季度 第一天或最后一天

/**
     * 获取季度 第一天或最后一天
     *
     * @param isFirst true获取开始时间 false获取结束时间
     * @return java.lang.String
     */
    public static ZonedDateTime setStartOrEndDayOfQuarter(ZonedDateTime dateTime, Boolean isFirst) {
        LocalDate localDate = dateTime.toLocalDate();
        Month month = localDate.getMonth();
        Month firstMonthOfQuarter = month.firstMonthOfQuarter();
        Month endMonthOfQuarter = Month.of(firstMonthOfQuarter.getValue() + 2);
        if (isFirst) {
            localDate = LocalDate.of(localDate.getYear(), firstMonthOfQuarter,
                    1);
        } else {
            localDate = LocalDate.of(localDate.getYear(), endMonthOfQuarter, endMonthOfQuarter.length(localDate.isLeapYear()));
        }
        return localDate.atStartOfDay((ZoneId.systemDefault()));
    }

3.测试代码

 public static void main(String[] args) {
//        System.out.println("hello");
//        ZonedDateTime currentStartQuarter = getStartOrEndDayOfQuarter(0, true);
//        System.out.println("本季度开始时间 ： " + currentStartQuarter);
//        ZonedDateTime currentEndQuarter = getStartOrEndDayOfQuarter(0, false);
//        System.out.println("本季度开始时间 ： " + currentEndQuarter);
//        ZonedDateTime startQuarter = getStartOrEndDayOfQuarter(-1, true);
//        System.out.println("本季度开始时间 ： " + startQuarter);
//        ZonedDateTime endQuarter = getStartOrEndDayOfQuarter(-1, false);
//        System.out.println("本季度开始时间 ： " + endQuarter);
        int monthValue = ZonedDateTime.now().getMonthValue();
        int dayValue = ZonedDateTime.now().getDayOfMonth();
        System.out.println(monthValue);
        System.out.println(dayValue);
        ZonedDateTime currentStartQuarter = getStartOrEndDayOfQuarter(0, true).plusMonths(+1).plusDays(+10);
        System.out.println(currentStartQuarter);
    }
