The java.io.BufferedWriter class is a subclass of
java.io.Writer that you chain to another Writer class to buffer characters. This allows more
efficient writing of text.
Each time you write to an unbuffered Writer,
there's a matching write to the underlying output stream. Therefore
it's a good idea to wrap a BufferedWriter around each
Writer whose write() operations are
expensive and that does not require immediate response, such as a
FileWriter. For example,
BufferedWriter bw = new BufferedWriter(new FileWriter("37.html"));
There are two constructors, one with a default buffer size of 8192 characters, and one that lets you specify the buffer size:
public BufferedWriter(Writer out)
public BufferedWriter(Writer out, int size)
The one new method in this class is newLine(). This
method that writes a platform dependent line terminator string, \n
on Unix, \r on the Mac, \r\n on Windows.
public String newLine() throws IOException
