java代码实现日期月份的间隔数

java计算两个月份的间隔代码如下

    public static void main(String[] args) throws ParseException {
        int monthSpace = monthPreiod("2021-01-12", "2022-12-01");
        System.out.println(monthSpace);
    }

    public static int monthPreiod(String date1, String date2)
            throws ParseException {
        int result = 0;
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        Calendar c1 = Calendar.getInstance();
        Calendar c2 = Calendar.getInstance();
        c1.setTime(sdf.parse(date1));
        c2.setTime(sdf.parse(date2));
        result = c2.get(Calendar.MONTH) - c1.get(Calendar.MONTH) + (c2.get(Calendar.YEAR) - c1.get(Calendar.YEAR)) * 12;
        return result == 0 ? 1 : Math.abs(result);
    }

结果显示23个月

很nice
