> The String.replaceAll(regex, other) can replace the string satisfying the "regex" with the given "other" string. However, if the given "regex" is a simple plain string (i.e., no special characters), another API String.replace(origin, other) is recommended as the former need to be compiled a head of time, which will cause additional overhead.
