如何拆分字符串 |(管道)在 Java 中 [英] How to split a string on | (pipe) in Java

问题描述

我有一个类似 |serialNo|checkDelta?|checkFuture?|checkThis?| 的字符串.

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

现在我使用下面的代码来分割字符串.

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，而我需要包含字母的字符串，例如 serialNo, checkDelta?, 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?我错过了什么吗?

How to get these? Am I missing something?

推荐答案

您必须转义管道字符 (split 将正则表达式作为参数，因此 "|" 是 控制字符):

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:结果数组的开头包含一个空字符串，因为您有|"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.
