如何分割字符串数组？ [英] How to split a String array?

问题描述

意向是采取当前行（字符串，其中包含逗号）替换为（修剪空格）空格，最后分裂存储字符串元素到数组。

为什么不这项工作？

 的String [] = TEXTLINE currentInputLine.replace（\\\\ S，）.split（）;
 

解决方案

我想你想的replaceAll而不是取代。

和的replaceAll（\\\\ S，）将删除所有的空格，而不仅仅是冗余的。如果这不是你想要的，你应该尝试的replaceAll（\\\\ S +，\\\\ S）或类似的东西。

Intention is to take a current line (String that contains commas), replace white space with "" (Trim space) and finally store split String elements into the array.

Why does not this work?

String[] textLine = currentInputLine.replace("\\s", "").split(",");

解决方案

I think you want replaceAll rather than replace.

And replaceAll("\\s","") will remove all spaces, not just the redundant ones. If that's not what you want, you should try replaceAll("\\s+","\\s") or something like that.
