使用Java获取两个日期之间的差异 [英] Get difference between two dates in months using Java

问题描述

我需要使用Java来获得两个日期之间的区别。

例如：

Startdate = 2013-04-03
enddate = 2013-05-03
结果应为1

如果间隔是

Startdate = 2013-04-03
enddate = 2014-04-03
结果应为12

使用以下代码，我可以在几天内得到结果。如何获取几个月？

  Date startDate = new Date（2013,2,2）; 
日期endDate =新日期（2013,3,2）; 
 int difInDays =（int）（（endDate.getTime（） -  startDate.getTime（））/（1000 * 60 * 60 * 24））; 
  

解决方案

如果您无法使用JodaTime，您可以以下内容：

  Calendar startCalendar = new GregorianCalendar（）; 
 startCalendar.setTime（startDate）; 
日历endCalendar = new GregorianCalendar（）; 
 endCalendar.setTime（endDate）; 
 
 int diffYear = endCalendar.get（Calendar.YEAR） -  startCalendar.get（Calendar.YEAR）; 
 int diffMonth = diffYear * 12 + endCalendar.get（Calendar.MONTH） -  startCalendar.get（Calendar.MONTH）; 
  

请注意，如果您的日期是2013-01-31和2013-02-01，您会得到这样一个月的距离，这可能或可能不是你想要的。

I need to get difference between two dates using Java. I need my result to be in months.

Example:

Startdate = 2013-04-03 enddate = 2013-05-03 Result should be 1

if the interval is

Startdate = 2013-04-03 enddate = 2014-04-03 Result should be 12

Using the following code I can get the results in days. How can I get in months?

Date startDate = new Date(2013,2,2);
Date endDate = new Date(2013,3,2);
int difInDays = (int) ((endDate.getTime() - startDate.getTime())/(1000*60*60*24));

解决方案

If you can't use JodaTime, you can do the following:

Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);

int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);

Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.
