On this document we will be showing a java example on how to use the newLine() method of BufferedWriter Class.The newLine() method is provided, which uses the platform’s own notion of line separator as defined by the system property line.separator.

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 linefeed. The following example shows the usage of java.io.BufferedReader.readline
