排序日期和时间值 [英] Sort date and time values

问题描述

简单地说，我有一个不同日期和时间的字符串数组.每个元素都具有以下格式:

Putting simply, I have a string array of different dates and times. Each element is of this format:

2015-08-27T22:24:31.903

2015-08-27T22:24:31.903

即YYYY-MM-DD T HH:MM:SS.MMM

That is, YYYY-MM-DDTHH:MM:SS.MMM

我正在对它们进行排序.有没有可用的默认方法可以对这种格式进行排序?

I'm sorting them. Is there a default method available to sort this format?

我现在正在做的是在 T 处分割字符串，将日期和时间转换为相应的时间戳，添加它们，然后对时间戳值进行排序.是否有针对这种格式的直接解析器?最好的解决方案是最欢迎的.

What I'm doing now is splitting the string at T, converting the date and time to respective timestamps, adding them and then sorting the timestamp values. Is there a direct parser for this format available? A better solution is most-welcome.

推荐答案

我有一个字符串数组.每个元素的格式均为:2015-08-27T22:24:31.903.有没有默认的方法可以对这种格式进行排序?

I have a string array. Each element is of this format: 2015-08-27T22:24:31.903. Is there a default method available to sort this format?

是的.由于ISO字符串的日期字段按大小降序排列，并且字段是固定宽度的，因此您可以直接使用

Yes. Since the ISO string has date fields in descending order of magnitude, and fields are fixed-width, you can simple sort the strings directly using Arrays.sort(Object[] a): Sorts the specified array of objects into ascending order, according to the natural ordering of its elements.

是否可以使用这种格式的直接解析器?

Is there a direct parser for this format available?

是的. LocalDateTime.parse(CharSequence text) :从诸如2007-12-03T10:15:30的文本字符串中获取LocalDateTime的实例.

Yes. LocalDateTime.parse(CharSequence text): Obtains an instance of LocalDateTime from a text string such as 2007-12-03T10:15:30.
