Cách sử dụng Google QPX API với Java để tìm kiếm chuyến bay?

Question

Tôi đang cố gắng xây dựng một mã Java đơn giản có các tùy chọn chuyến bay bằng cách sử dụng API Google QPX, cho chuyến bay từ New York đến Luân Đôn. Tôi đã đăng ký với Google và nhận API_key.

Tôi đã đọc tài liệu, nhưng rất tiếc, tôi không thể tìm thấy bất kỳ ví dụ nào cho tôi biết cách thực hiện.

Ở đây những gì tôi đã cố gắng cho đến nay:

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? 

    } 
} 

tôi sẽ đánh giá cao nếu ai đó có thể giúp tôi để hoàn thành mã. Cảm ơn trước.
