Java - 一次拆分和修剪 [英] Java - Split and trim in one shot

问题描述

我有一个这样的字符串:String attributes = " foo boo, faa baa, fii bii," 我想得到这样的结果:

I have a String like this : String attributes = " foo boo, faa baa, fii bii," I want to get a result like this :

String[] result = {"foo boo", "faa baa", "fii bii"};

所以我的问题是如何在我已经分裂的一个镜头中进行分裂和修剪:

So my issue is how should to make split and trim in one shot i already split:

String[] result = attributes.split(",");

但是 spaces 仍然在结果中:

But the spaces still in the result :

String[] result = {" foo boo", " faa baa", " fii bii"};
                    ^           ^           ^

我知道我们可以制作一个循环并为每个人制作trim，但我想在镜头中制作它.

I know that we can make a loop and make trim for every one but I want to makes it in shot.

推荐答案

使用正则表达式 s*,s* 进行拆分.

Use regular expression s*,s* for splitting.

String result[] = attributes.split("\s*,\s*");

对于初始和尾随空格
先前的解决方案仍然留下初始和尾随空格.因此，如果我们期望它们中的任何一个，那么我们可以使用以下解决方案将其删除:

For Initial and Trailing Whitespaces
The previous solution still leaves initial and trailing white-spaces. So if we're expecting any of them, then we can use the following solution to remove the same:

String result[] = attributes.trim().split("\s*,\s*");
