Java如何获取Joda-Time中两个日期之间的月数？
下面的代码向您展示如何使用Months该类来计算两个日期之间的月份差异。
package org.nhooo.example.joda;
import org.joda.time.DateMidnight;
import org.joda.time.LocalDate;
import org.joda.time.Months;
import java.util.Date;
public class MonthsBetweenDemo {
public static void main(String[] args) {
//创建开始日期和结束日期的实例。
DateMidnight start = new DateMidnight("2019-01-01");
DateMidnight end = new DateMidnight(new Date());
//在这些日期之间获取月份。
int months = Months.monthsBetween(start, end).getMonths();
//打印结果。
System.out.println("Months between " +
start.toString("yyyy-MM-dd") + " and " +
end.toString("yyyy-MM-dd") + " = " +
months + " month(s)");
//使用LocalDate对象。
LocalDate date1 = LocalDate.parse("2019-03-01");
LocalDate date2 = LocalDate.now();
months = Months.monthsBetween(date1, date2).getMonths();
//打印结果。
System.out.println("Months between " +
date1.toString("yyyy-MM-dd") + " and " +
date2.toString("yyyy-MM-dd") + " = " +
months + " month(s)");
}
}这是我们程序的输出：
Months between 2019-01-01 and 2019-07-22 = 6 month(s) Months between 2019-03-01 and 2019-07-22 = 4 month(s)
