如何在|上分割字符串(管道)在Java中 [英] How to split a string on | (pipe) in Java

问题描述

我有一个像 | serialNo | checkDelta?| checkFuture?| checkThis?| 之类的字符串.

I have a string like |serialNo|checkDelta?|checkFuture?|checkThis?|.

现在我正在使用以下代码分割字符串.

Now I am using the following code to split the string.

String [] splitString = str.split("|");

但是当我使用它时，我得到包含每个字符的字符串数组，而我需要包含诸如 serialNo ， checkDelta?，的字母的字符串checkFuture?， checkthis?.

but when I use this I get array of string that contains each and every character, whereas I need string which contains letter like serialNo, checkDelta?, checkFuture?, checkthis?.

如何获得这些?我想念什么吗?

How to get these? Am I missing something?

推荐答案

您必须转义管道字符(

You'll have to escape your pipe character (split takes a regular expression as argument and therefore "|" is a control character):

str.split("\\|");

请注意:由于您使用"|"，因此结果数组的开头包含一个空字符串.在字符串的开头.

Please note: the resulting array contains an empty string at the beginning since you have "|" at start of your string.
