Buffering

• When reading from a file it is often better to read large chunks at a time.
• When writing, the buffer is sent out when its full.
• You must be careful when using buffering on an output stream to write to sockets. Always flush when you are done.

//Read
BufferedReader input = new BufferedReader (new InputStreamReader(System.in));

//Write
Writer out= newBufferedWriter(new FileWriter("file.out"));

//Write a system-dependent newline. DANGER!!!
out.newLine();

• When talking HTTP you always want to send \r\n
