如何使用Java按小时：分钟：秒分割字符串

Question

I've got strings that have the following format:

Text 11:54:02 Text
[1]"Fri Sep 19 11:07:24 +"RT @OliverBullough: Andrei Yakunin, investor son of Putin's friend Vladimir, on Russian deals: \"2014 is lost, 2015 is effectively lost.\" ht\u2026"

Where Text is just normal text and the 11:54:02 is the time. Now the time varies constantly, so we could have 11:53:11 or 02:01:01 etc. I would like to know if it is possible to split by this time ie

[Text][Time][Text]
[[1]"Fri Sep 19] [11:07:24][ +"RT @OliverBullough: Andrei Yakunin, investor son of Putin's friend Vladimir, on Russian deals: \"2014 is lost, 2015 is effectively lost.\" ht\u2026"]

So that I can just read the first and second text values. I've tried using the following split but it doesn't seem to work:

String[] Timesplit = fileContent.split("0-9:0-9:0-9");

Ideally I would want Timesplit[0] to have [1]"Fri Sep 19 and Timesplit[2] to have +"RT @OliverBullough: Andrei Yakunin, investor son of Putin's friend Vladimir, on Russian deals: \\"2014 is lost, 2015 is effectively lost.\\" ht\…"

Is it possible to split the data?

Answer 1

You can just split the string by ":"

String[] split = fileContent.split(":");

So "11:54:02" will return ["11", "54", "02"]

"0-9:0-9:0-9" doesn't seem to be a regex, which means fileContentSplit("0-9:0-9:0-9") will actually try to find "0-9:0-9:0-9" within the string and split it by that.

Answer 2

尝试写[0-9]而不是0-9。

Answer 3

Use this, String[] split = fileContent.split("[0-9][0-9]:[0-9][0-9]:[0-9][0-9]");

Thanks.

Answer 4

i used this regex

([0-9]{2}):([0-9]{2}):([0-9]{2})

.

String fileContent="[1]\"Fri Sep 19 11:07:24 +\"RT @OliverBullough: Andrei Yakunin, investor son of Putin's friend Vladimir, on Russian deals: \\\"2014 is lost, 2015 is effectively lost.\\\" ht\\u2026\"";
String[] Timesplit = fileContent.split("([0-9]{2}):([0-9]{2}):([0-9]{2})");
System.out.println(Timesplit[0]);
System.out.println(Timesplit[1]);

output>>

[1]"Fri Sep 19 
 +"RT @OliverBullough: Andrei Yakunin, investor son of Putin's friend Vladimir, on Russian deals: \"2014 is lost, 2015 is effectively lost.\" ht\u2026"
