Android : What will happen , if i will comment onStartCommand during writing a service?

I am trying to start an Android service code and i have commented onStartCommand , so do the service will keep running or it will stop itself in the middle way.

MyCode:

@Override 
public int onStartCommand(Intent intent, int flags, int startId) 
{

  //super.onStartCommand(intent, flags, startId);

  return START_STICKY; 

}

Please let me know , the possible situation during service running in the system.
