JAVA7,8两个日期对比是否跨过几个月份

public static void main(String[] args) {

// 示例：假设有两个时间点 t1 和t2

        String t1 ="2023-01-01";

        String t2 ="2023-02-28";

        if (isMoreThanTwoMonths(t1, t2) >=2) {

System.out.println("=======超过两个月了哦==========");

        }else {

System.out.println("=======没有超过两个月==========");

        }

}
