基于开括号的Java中的Split String

Question

Existing string:

stringToBeCleaned = author(A, UniqueVar1), author(B, UniqueVar1);

Expected String:

stringAfterCleaned = author(A, UniqueVar1)^author(B, UniqueVar1);

The method I wanted to try was split the string and join it appending the exponential symbol. But I have problems in splitting.

split = stringToBeCleaned.split(", ");

This does not give the required split.

split = stringToBeCleaned.split("), ");

This split throws error for the invalid regex, because the braces are not closed Is there any way to achieve this. Any suggestions would be helpful.

Answer 1

You just need to escape the parenthesis:

split = stringToBeCleaned.split("\\), ");

Or you can just replace the comma without regex:

stringToBeCleaned = stringToBeCleaned.replace("), ", ")^");
