Servlet response write vs print? Which is better?

问题

I am having a string which needs to be sent as response from a servlet & I am having two approaches to send response back from it.

First is using PrintWriter.

response.getWriter().print(responseString);

Second is using OutputStream.

 byte[] byteResponse = responseString.getBytes(Charset.forName("UTF-8"));
 response.getOutputStream().write(byteResponse);

I want to know which is better and efficient way of sending response?

Please suggest.

回答1:

Use an OutputStream for binary data, and a Writer for text.

回答2:

I am having a string specifies that you wish to write a string so i suggest the PrintWriter object

 //prints text data to screen (browser)
 PrintWriter printer = response.getWriter();
 printer.print(string);
 //print again if you wish
 printer.print("Welcome blahblah");
 //close afterwards if you don't mind.
 printer.close();

so if you wish to write text to browser, PrintWriter works just fine, fast and simple.
