Java 获取两个日期之间的所有月份 (年月)

    
    public static List getMonthBetweenDate(String startTime, String endTime){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM");
        // 声明保存日期集合
        List list = new ArrayList();
        try {
            // 转化成日期类型
            Date startDate = sdf.parse(startTime);
            Date endDate = sdf.parse(endTime);

            //用Calendar 进行日期比较判断
            Calendar calendar = Calendar.getInstance();
            while (startDate.getTime()<=endDate.getTime()){
                // 把日期添加到集合
                list.add(sdf.format(startDate));
                // 设置日期
                calendar.setTime(startDate);
                //把日期增加一天
                calendar.add(Calendar.MONTH, 1);
                // 获取增加后的日期
                startDate=calendar.getTime();
            }
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return list;
    }

    public static void main(String[] args) throws ParseException {
        String startStr = "2021-02-26";
        String endStr = "2022-03-09";
        List list = getMonthBetweenDate(startStr, endStr);
        System.out.println(list);
    }
