Help need to learn how to do this?

Question

1. Name, which has fields:
    - String lastname
    - String firstname
2. Address, which has fields:
    - int stnum
    - String street
    - String city
    - String postalCode
3. PassengerRecord, which has fields:
    - int passengerID
    - Name passengerName
    - Address passengerAddr
4. Passengers, which has fields:
    - int numpassengers
    - PassengerRecord[] passRecords
5. TrainStation, which has fields:
    - String  trainStationName
    - Address trainStationAddr
    - Passengers passengerRecs
The main routine, in class MainClass, MUST look like this:
public static void main(String[] args){
  TrainStation station = new TrainStation();
  station.readIn();
  System.out.printf("station=%s",station.toString());
}//main
which creates an instance of class TrainStation,
then calls the readIn() function of that TrainStation object which will:
1.  read in the  trainStationName, which is a String
2.  read in the trainStationAddr, by calling trainStationAddr.readIn()
3.  read in passengerRecs, by calling passengerRecs.readIn() which
    reads in the number of PassengerRecord objects and
    creates the array passRecords.
    Then, passengerRecs.readIn() calls readIn() on each
    passenger record in array passRecords, which will
    in turn read in the passengerID,
    and call passengerName.readIn(), and passengerAddr.readIn()
After calling station.readIn(), main will print out all of
the contents of the TrainStation object pointed to by printing
station.toString().can someone help me learn this fast like any places where i can read and learn how to do this?

Otherwise I would review any handouts or online material available that saved you from writing notes that day.
