推荐答案

在不使用任何第三方库的情况下，您基本上必须编写自己的 RFC 5545 )解析器，复制这些第三方图书馆的作品.不会很有趣.

Without using any third party libraries, you'll have basically have to write your own iCalendar (see RFC 5545) parser, reproducing the work of those third party libraries. It won't be fun.

诚然，我自己对 iCal4j 的体验并不令人愉快-但我不会开始写我的使用 java.util.Date 和 java.util.Calendar 从头开始拥有自己的解析器.您也许认为值得使用 Joda Time 来表示各种形式的iCalendar解析器方面(日期"，时间"等)，因为与内置API相比，它是一个更好的API.但是同样，您可能会发现iCal4j足以满足您的目的.

Admittedly my own experiences with iCal4j haven't been terribly pleasant - but I wouldn't start writing my own parser from scratch using java.util.Date and java.util.Calendar. You may find it's worth writing an iCalendar parser using Joda Time to represent the various aspects ("a date", "a time" etc) as that's a much nicer API to work with than the built-in ones... but equally you may find that iCal4j is good enough for your purposes.
