The difference between response.getWriter().write() and response.getWriter().print()

• What response.getWriter() returns is PrintWriter, which is a print output stream.
• response.getWriter() .print(), not only can print output in text format (including html tags), but also convert an object into binary byte output with default encoding
• response.getWriter().writer(), can only print out text format (including html tags), not objects.

<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
     $("#button1").click(function(){
             $.get("AJAXServer",null,function(data){
                 alert(data);
                $("#info").html(data);
            });
           });
    })
</ script > 
</ head > 
< body > 
< input type = "button" id = "button1" value = "Click me to get server response information" onclick = "a()" ; /> 
< div id = "infd

Output object server-side code:

        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          Person person = new Person();
          person.setName("sjl");
          response.getWrier().print(person);}

 

Running result: 
server.Person@5bd5ab 
If you use response.getWriter().writer(), the code will report an error

 

Server-side code that demonstrates text information:

response.getWriter().write("this is <b>server</b> response");
/**response.getWriter().print("this is<b>server2</b>response")*/;

 

Output result 
this is server response

The output of the commented code is the same
