java.util.regex.PatternSyntaxException: Unmatched closing ')' : during string.split operation

Question

I am trying to perform a split similar the following:

String str = "({Somestring 1 with a lot of braces and commas}),({Somestring 12with a lot of braces and commas})";
println str.split("}),({");

But i see:

java.util.regex.PatternSyntaxException: Unmatched closing ')' near index 0 }),({

Clearly , my string is being treated as a regular expression.

Is there a way i can escape this string?

Answer 1

the character ( and ) and { and } are special character in regexp. you have to escape these:

println str.split("\\}\\),\\(\\{");
