Java Fundamentals Hardening IO Stream Note 39: The special function of the character stream buffer stream

1. Special methods for character buffer streams

BufferedWriter:

1  Public void newLine (): depending on the system to determine the line break

BufferedReader:

1  Public String readLine (): reads one row of data at a time

A string containing the contents of the row, with no line terminator, or null if the end of the stream has been reached
