      byteSize - the maximum number of bytes allowed in UTF-8 encoding
      Returns:
      the original string if it fits within the byte limit, a truncated version otherwise, or null if input is null

    • convertToSetLong

      public static Set<Long> convertToSetLong(String stringToFormat, String regex)

      Parameters:
      stringToFormat - the input string containing comma-separated numbers (spaces are ignored)
      regex - the regex pattern to validate the input format (e.g., "\\d+(,\\d+)*+")
