问题描述
我正在尝试按字符 "}{" 拆分字符串.但是我收到一个错误:
I'm trying to split a string in by the characters "}{". However I am getting an error:
> val string = "{one}{two}".split("}{") java.util.regex.PatternSyntaxException: Illegal repetition near index 0 }{ ^我不想使用正则表达式或任何东西.我尝试使用 "\}\{" 并且它也不起作用.
I am not trying to use regex or anything. I tried using "\}\{" and it also doesn't work.
推荐答案嗯...原因是 split 将其参数字符串视为正则表达式.
Well... the reason is that split treats its parameter string as a regular expression.
现在,{ 和 } 都是正则表达式中的特殊字符.
Now, both { and } are special character in regular expressions.
所以你将不得不跳过 split 的参数的正则表达式世界的特殊字符,像这样,
So you will have to skip the special characters of regex world for split's argument, like this,
val string = "{one}{two}".split("\\}\\{") // string: Array[String] = Array({one, two})更多推荐
