Answers a String representing the next line of text available in this BufferedReader. A line is represented by 0 or more characters followed by '\n', '\r', "\n\r" or end of stream. The String does not include the newline sequence. @return the contents of the line or null if no characters were readbefore end of stream. @throws IOException If a problem occurs reading from this stream.
