两个Java日期之间的天数差异？ [英] Difference in Days between two Java dates?

问题描述

我想了解两个Java Date对象之间的区别。我使用了Joda-Time库。但是问题是我得到的天数差异大于实际的天数差异。

I want to get the difference between two Java Date objects. I've used Joda-Time library. But the problem is that I'm getting the Days greater difference than that of actual day difference.

这是我的代码段：

DateFormat formatter = new SimpleDateFormat("mm/dd/yyyy");

Date someDate=new Date();
Date today = Calendar.getInstance().getTime();

try     {
    someDate = formatter.parse("06/22/2010");
}
catch(ParseException pe)    {
    System.out.println("Parser Exception");
}

int days = Days.daysBetween(new DateTime(someDate), new DateTime(today)).getDays();

System.out.println(" Days Between " + someDate + " : " + today + " - " + days);

这是我的输出：

 Days Between Fri Jan 22 00:06:00 IST 2010 : Sun Jul 25 19:27:01 IST 2010 - 184

在这里，为什么将 06/22/2010设为1月22日？有人遇到类似的问题吗？

Here, Why does it takes "06/22/2010" as Jan 22? Does anyone face similar problem?

帮帮我的朋友..提前谢谢。.

Help me friends.. Thanx in advance..

推荐答案

月份是MM

在您的情况下：

DateFormat formatter = new
SimpleDateFormat（ MM / dd / yyyy）;

DateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
