Calling a method after 10 seconds

Question

Hello,
I need to call a method after 10 seconds. That is to make sure that if one particular field is updated, say 3 times in a window of 10 seconds, I should just be able to take the last value and process it, in my ajax app. I am so far using the Timer class, but the problem is, it ticks off a thread for every single request to be processed after 10 seconds and processes all the 3 requests, where as I should just be running that method once for the last request. Could you please help me with this ?
Cant do this at the client level, for the page may be closed within those 10 seconds of the event and the setTimeout wont work then.
This is what I made so far.:
final Map<String, Object> mp = new HashMap<String, Object>();
if(form.getEmpId() != null )
            mp.put(form.getEmpId().toString(), form);
            new java.util.Timer().schedule(new java.util.TimerTask()
               public void run()
                  EmpForm form1 = (EmpForm)mp.get(empId.toString());
                  String empId = form1.getempId().toString();
                  String value1Changed = form1.getValue1Changed().toString();
                  String value2Changed = form1.getValue2Changed().toString();
                  myService.changeData(empId, value1Changed, value2Changed),
            }, 10000);
         }

My recommendation is that you share an AtomicReference between your timer and the listener that is receiving the updates. This way, the listener can just update the value, and the timer uses the latest one when it wakes upOk, out of my limited understanding, I looked up AtmoicReference and found it a class. I think I cant use that since I am maintaining a list of empIds against the object that holds their data in a hashmap, expecting the map to override the empId on the second request. So, I made a final map and thought Id just push the timer scheduler method in another method, but the problem is, for me to ask that thread (which I expect to run after 10 seconds of my calling) to run, I need to call it somewhere, and as soon as I get a request I am calling the method which runs/ticks off the thread.
I was thinking that since I am passing and using a final map (that I declared as a class level variable), I will be able to put update the map object and whenever the thread runs, will fetch the latest value (of the empId) in the map. But I guess I am doing it wrong. :(
