java - Using Swing Timer to delay task -

i using swing timer delay task specific period of time. time interval decided user.

in gui, have spinnerdatemodel accept time @ task has performed.

spinnerdatemodel date = new spinnerdatemodel();         jspinner spinner = new jspinner(date);                   frame.getcontentpane().add(spinner);                     date futuredate = date.getdate(); 

now, timer has arguments timer(int delay, actionlistener task)

actionlistener task = new actionlistener(){                      @override                     public void actionperformed(actionevent arg0) {                          //send function                     }                  };                 timer timer = new timer(delay, task);                 timer.setrepeats(false);                                 timer.start(); 

how set delay time specified user?

with checking prevent negative delay, like:

delay=math.max(0,futuredate.gettime()-system.currenttimemillis()); delay=math.min(delay,integer.max_value); // or: //   if(delay>integer.max_value) { throw new exception-of-some-sort } timer timer=new timer((int)delay,task); 

should trick.

this calculate delay based on number of milliseconds until (presumed future) date selected user.
