how to maintain count value over a Browser using HttpSession in java? -

i want maintain onw count value on http browser. example :

if browser once open , click on submit button make count one. again click on button make count two. , want count should less two.

consider count : private static int count & maxcount : private int maxcount = 3 code:

 protected void processrequest(httpservletrequest request,httpservletresponse response)         throws servletexception, ioexception {      httpsession session = request.getsession();      session.setattribute("count", ++count);      if(session.getattribute("count") <= maxcount){          //proccess stuff      }else{         //give maxcount completed message      }  } 

it work fine when open browser first time if open browser in window showing me maxcount completed message

i recognize count static variable , gets memory once , can this. want count value again 0 when open in window of browser?

you can change this.

protected void processrequest(httpservletrequest request,httpservletresponse response)         throws servletexception, ioexception {      httpsession session = request.getsession();      integer count = (integer)session.getattribute("count");       if( count == null) {          count  = 1;          session.setattribute("count", count);         }      if(count <= maxcount){          session.setattribute("count", ++count);          // other stuff.      }else{         //give maxcount completed message      }  } 

no need have static variable or private variable.
