获得当前季度和已过季度的起始和结束时间

获得当前季度和已过季度的起始时间和结束时间

如：当前时间为：2018-09-08 15:12:00，那么当前季度为第三季度，这时要得到是

第一季度："2018-01-01 00:00:00":"2018-03-31 23:59:59"，

第二季度："2018-04-01 00:00:00":"2018-06-30 23:59:59"，

第三季度："2018-07-01 00:00:00":"2018-08-25 09:27:46"；

代码如下：

　　public static String[] getEveryQuarterStartAndEndTime(){
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Calendar calendar = getInstance();
        Map<String, Object> params = new HashMap<String, Object>();
        String currentTime = formatter.format(calendar.getTime());
        int year = calendar.get(Calendar.YEAR);
        int currentMonth = calendar.get(Calendar.MONTH);
        String startTime = "";
        String endTime = "";

        int season = (currentMonth)/3+1;
        String[] startAndEndSeason = new String[season];

        for (int i = 0; i < season; i++) {
            params.clear();
            switch (i) {
                case 0:
                    //起始时间
                    calendar.set(year, 0, 1, 0, 0, 0);
                    startTime = formatter.format(calendar.getTime());
                    //结束时间
                    calendar.set(year, 2, 31, 23, 59, 59);
                    endTime = formatter.format(calendar.getTime());
                    params.put(startTime, endTime);
                    startAndEndSeason[i] = JSON.toJSONString(params);
                    break;
                case 1:
                    //起始时间
                    calendar.set(year, 3, 1, 0, 0, 0);
                    startTime = formatter.format(calendar.getTime());
                    //结束时间
                    calendar.set(year, 5, 30, 23, 59, 59);
                    endTime = formatter.format(calendar.getTime());
                    params.put(startTime, endTime);
                    startAndEndSeason[i] = JSON.toJSONString(params);
                    break;
                case 2:
                    //起始时间
                    calendar.set(year, 6, 1, 0, 0, 0);
                    startTime = formatter.format(calendar.getTime());
                    params.put(startTime, currentTime);
                    //结束时间
                    calendar.set(year, 8, 30, 23, 59, 59);
                    endTime = formatter.format(calendar.getTime());
                    params.put(startTime, endTime);
                    startAndEndSeason[i] = JSON.toJSONString(params);
                    break;
                case 3:
                    //起始时间
                    calendar.set(year, 9, 1, 0, 0, 0);
                    startTime = formatter.format(calendar.getTime());
                    params.put(startTime, currentTime);
                    //结束时间
                    calendar.set(year, 11, 31, 23, 59, 59);
                    endTime = formatter.format(calendar.getTime());
                    params.put(startTime, endTime);
                    startAndEndSeason[i] = JSON.toJSONString(params);
                    break;
                default:
                    break;
            }
        }
        return startAndEndSeason;
    }

 

 调用执行方法：

public static void main(String[] args) {
    String[] strs = getEveryQuarterStartAndEndTime();
    　　for (String str : strs) {
　　　　　　 Map<String, Object> params = JSON.parseObject(str);
        　　System.err.println(str);
    }
}

运行结果为：
