从java.util.date转换为JodaTime

Question

I want to convert a java.util.Date to JodaTime so as to carry out subtractions between dates. Is there a good concise way to convert from Date to JodaTime ?

Answer 1

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null , though, otherwise it acts like new DateTime() - I really don't like that.

Answer 2

Each datetime class provides a variety of constructors. These include the Object constructor. This allows you to construct, for example, DateTime from the following objects:

* Date - a JDK instant
* Calendar - a JDK calendar
* String - in ISO8601 format
* Long - in milliseconds
* any Joda-Time datetime class
