使用Joda时间比较两个日期 [英] Comparing two dates using Joda time

问题描述

我想比较两个日期，但我遇到麻烦。 1日期是从 java.util.date 对象创建的，另一个是手工制作的。以下代码是一个例子：

I want to compare two dates, however I'm running into trouble. 1 date is created from a java.util.date object and the other is manually crafted. The following code is an example:

Date ds = new Date();
DateTime d = new DateTime(ds);

DateTime e = new DateTime(2012,12,07, 0, 0);
System.out.println(d.isEqual(e));

但测试结果是 false 。我猜这是因为时间。我如何检查这两个日期是否相等（我的意思是年份，月份，日期是否相同）？

However the test turns out false. I am guessing that it is because of the time. How can I check if these two dates are equal to each other (I mean the Year, month, date are identical)?

推荐答案

System.out.println(d.toDateMidnight().isEqual(e.toDateMidnight()));

或

System.out.println(d.withTimeAtStartOfDay().isEqual(e.withTimeAtStartOfDay()));
