How to convert java.util.Date objects into Calendar objects?
提问by Click Upvote
I'm using the PrettyTimejava library for a variety of date/time processing in my java app, such as converting MySQL format dates/datetime strings into java dates, or the vice versa.
我在我的 java 应用程序中使用PrettyTimejava 库进行各种日期/时间处理，例如将 MySQL 格式的日期/日期时间字符串转换为 java 日期，反之亦然。
However, I see that date.getYear(), date.getMonth(), etc, are all deprecated, and it says to use Calendar instead. But PrettyTime only returns its results as Date objects, and I see no way to convert the Date objects into calendar objects.
但是，我看到date.getYear(), date.getMonth()等都已弃用，它说要改用 Calendar。但是 PrettyTime 仅将其结果作为 Date 对象返回，我认为无法将 Date 对象转换为日历对象。
In the documentation for Calendar, the only mention I see of Dateis the method setTime(Date date), but the method name is ambigious, and the documentation is not clear on what calling this method would actually do. Obviously I can't just do calendar.set( date.getYear(), date.getMonth(), ..)etc, as those methods of Dateare deprecated.
在Calendar的文档中，我看到的唯一提及Date是方法setTime(Date date)，但方法名称不明确，并且文档不清楚调用此方法实际上会做什么。显然我不能只做calendar.set( date.getYear(), date.getMonth(), ..)等，因为这些方法已Date被弃用。
So how can I convert a given Date object to Calendar?
那么如何将给定的 Date 对象转换为 Calendar？

Calendar cal = Calendar.getInstance();
cal.setTime(date);
You can get the calendar in different locales as well if you want.
如果需要，您也可以在不同的语言环境中获取日历。
You could also do
你也可以这样做
cal.setTimeInMillis(date.getTime());
