When i create an appointment i will select a contact name the related contact should be update with the values in the appointment fields. can any one help??

Answer 1

What part are you having problems with?

It sounds like you should be able to use standard variable assignment to do this. If appointments must always have a contact, you could perhaps do this in the appointment's constructor:

function Appointment(contact)
{
   ...
   contact.nextAppointmentDate = this.date;
}

otherwise, you could do this in the code that creates the appointment:

Appointment appointment = new Appointment(date);
contact.nextAppointmentDate = appointment.date;

I'm not really sure whether you're asking about best practices here in general, or about the specific wiring, or if there's an additional complexity that you haven't mentioned. Is there a reason why you can't simply update the fields?
