        System.out.println("month:"+ month);
        System.out.println("month+monDif:" + (month+monDif));
 
方法 2 (推荐， 计算时还会把天也计算上)
 
		LocalDate afterDate = LocalDate.of(2021, 1, 9);
        LocalDate beforeDate = LocalDate.of(2019, 2, 10);
        long betweenMONTHS = ChronoUnit.MONTHS.between(beforeDate, afterDate);
        long between1YEARS = ChronoUnit.YEARS.between(beforeDate, afterDate);
        long between1DAYS = ChronoUnit.DAYS.between(beforeDate, afterDate);
        System.out.println(betweenMONTHS);
        System.out.println(between1YEARS);
        System.out.println(between1DAYS);

要求 Java 8 中两个 LocalDateTime 类型时间相差的月数，可以使用以下代码：
long monthsBetween = ChronoUnit.MONTHS.between(dateTime1, dateTime2);
其中，dateTime1 和 dateTime2 是你想要比较的两个 LocalDateTime 类型的时间。
这段代码会返回一个 long 类型的数字，表示两个...

迂回战术：获取两个日期之间的天数。除以7等于相隔多少周。

import java.time.LocalDate;
import java.time.Month;

public class DateUtils {
    public static long daysBetween(LocalDate startDate, LocalDate endDate) {
        return ChronoUnit.DAYS.between(startDate, endDate);
// 调用方法
LocalDate startDate = LocalDate.of(2021, 1, 1);
LocalDate endDate = LocalDate.of(2021, 1, 10);
long days = DateUtils.daysBetween(startDate, endDate);
System.out.println("相差天数：" + days);
以上代码中，我们使用了Java 8中的日期类LocalDate和ChronoUnit来计算两个日期之间相差的天数。其中，LocalDate表示一个日期，ChronoUnit.DAYS表示计算两个日期之间相差的天数。
