A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a line feed:contentReferenceoaicite:10{index=10}. The line-termination characters are not included in the returned string.
Return
a String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached:contentReferenceoaicite:11{index=11}.
Throws
IOException
if an I/O error occurs.
