You need to initialize your

t

first.

Change

try {
        t.schedule(timertask, d.getDate(), 1000);
    } catch (Exception e) {
        e.printStackTrace();
    }

To

try 
 {
    Timer t=new Timer();
    t.schedule(timertask, d.getDate(), 1000);
 } 
catch (Exception e) 
 {
   e.printStackTrace();
 }
