Scala Pattern Syntax Exception

Question

I\'m trying to split a string in by the characters \"}{\". However I am getting an error:

> val string = \"{one}{two}\".split(\"}{\")
java.util.r         


        

Answer 1

Well... the reason is that split treats its parameter string as a regular expression.

Now, both { and } are special character in regular expressions.

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})
