java - Is a PrintWriter a BufferedWriter -

Actually I would like to know whether PrintWriter is a buffer author or not. I have seen the code as PrintWriter pw = new PrintWriter (new buffer viter); however:

parameter: file - file to use If the file exists as the author's destination, it will be reduced to zero size; Otherwise, a new file will be created. The output will be written in the file and buffer will be done. < P> Bottom line: I think printwire is called "buffer" from Javadock (root See Ran) and if I can not touch the don print, it is not printed. Do you confirm my thesis? Why there is some code in that situation: PrintWriter pw = new PrintWriter (new buffer vetter (new flumerwriter (file)); legacy code?

Thanks in advance

Technically, this is not a BufferedWriter . It spreads directly to author . It is said, it seems Person can be is Based on a BufferedWriter constructor to use . A string :

  monitors the constructor passing through the public PrintWriter (string filename) for the tester throws FileNotFoundException {This (New BufferedWriter (New OutputStream Water ( New FileOutputStream (fileName))), false); }   
 Besides, you are not using Constructor for Jawadock, which you have linked. You have used Constructor which takes a  Writer  does not use a  BufferedWriter . This is its source code:
