The use and difference of outputstream and PrintWriter

1.OutputStream

Use steps: Get output stream set Chinese convert a string to a byte array call Outputstream.write ()

Here only the contents of the Doget method are posted:

    protected void doget (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException c2/>//gets OutputStream output stream
        outputstream outputstream = Response.getoutputstream ();
        Set Chinese
         response.setheader ("Content-type", "Text/html;charset=utf-8");
         String data = "Hello, here is the OutputStream way to the page output content";
        Converts a character to an array of bytes and specifies the UTF-8 encoding
         byte[] Databytearr = data.getbytes ("UTF-8");  output
         outputstream.write (Databytearr);
    }

2.PrintWriter

Using steps: Set document type and encoding to get getwriter () output

is also the content that only pastes the Doget method:

Set the response content type and encoding mode
response.setcontenttype ("Text/html;charset=utf-8");
PrintWriter out = Response.getwriter ();
Out.println ("Hello, here is the PrintWriter way to the page output");

3. Summary

The outputstream is output in bytes, and the PrintWriter is output in character form.
