本文展示了如何使用Java的Collections.sort方法和Comparator接口，根据推文的创建日期对推文列表进行降序排序。

For example, Tweet entity has two properties: Id, tweetCreateDate. I have a list of tweets, I need to sort them by tweetCreateDate desc. Here is the way I do it.

Collections.sort(tweets, new Comparator<Tweet>() {
	public int compare(Tweet t1, Tweet t2) {
		return t2.getTweetCreateDate().compareTo(t1.getTweetCreateDate());
	}
});
