Java获取两个日期之间的所有月份

    public static List<String> getMonthBetween(String minDate, String maxDate) throws ParseException {
        ArrayList<String> result = new ArrayList<String>();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM");//格式化为年月
 
        Calendar min = Calendar.getInstance();
        Calendar max = Calendar.getInstance();
 
        min.setTime(sdf.parse(minDate));
        min.set(min.get(Calendar.YEAR), min.get(Calendar.MONTH), 1);
 
        max.setTime(sdf.parse(maxDate));
        max.set(max.get(Calendar.YEAR), max.get(Calendar.MONTH), 2);
 
        Calendar curr = min;
        while (curr.before(max)) {
            result.add(sdf.format(curr.getTime()));
            curr.add(Calendar.MONTH, 1);
        }
 
        return result;
    }

复制上面的代码，到你项目里可以直接使用

演示：

System.out.println(DateBuilder.getMonthBetween("2020-01-01","2020-03-02"));

输出：

[2020-01, 2020-02, 2020-03]
