Come utilizzare l'API QPX di Google con Java per la ricerca di voli?

Question

Sto cercando di creare un semplice codice Java che ottenga le opzioni di volo utilizzando l'API QPX di Google, per il volo da New York a Londra. Mi sono registrato con Google e ho ottenuto API_key.

Ho letto la documentazione, ma sfortunatamente non ho trovato nessun esempio che mi indichi come farlo.

Ecco quello che ho provato finora:

import com.google.api.services.qpxExpress.model.*; 
import java.util.*; 

public class Main 
{ 
    public static void main(String[] args) 
    { 
     // Passengers 
     PassengerCounts passengers = new PassengerCounts(); 
     passengers.setAdultCount(2); 

     // Slice 
     List<SliceInput> slices = new ArrayList<SliceInput>(); 

     SliceInput slice = new SliceInput(); 
     slice.setOrigin("JFK"); // John Kennedy Airport in Ney York 
     slice.setDestination("LHR"); // London Heathrow 
     slice.setDate("2015-07-01"); 
     slices.add(slice); 


     // Options request 
     TripOptionsRequest tripOptions = new TripOptionsRequest(); 
     tripOptions.setPassengers(passengers); 
     tripOptions.setSlice(slices); 


     // Search request 
     TripsSearchRequest tripSearchReq = new TripsSearchRequest(); 
     tripSearchReq.setRequest(tripOptions); 

     // Next steps? 
     // Setting up QPXExpress? 

    } 
} 

io sarò grato se qualcuno mi può aiutare a completare il codice. Grazie in anticipo.
