尝试用Java简单写一个航空客运订票系统

好的，我可以为您提供一些基本的思路和代码示例。首先，我们需要定义一些基本的实体类，如航班、乘客、座位等。以下是一个简单的代码示例：

1. 定义航班类

public class Flight {
    private String flightNumber;
    private String departureCity;
    private String arrivalCity;
    private Date departureTime;
    private Date arrivalTime;
    private int availableSeats;
    // 省略构造函数和getter/setter方法
}

2. 定义乘客类

public class Passenger {
    private String name;
    private String idNumber;
    private String phoneNumber;
    // 省略构造函数和getter/setter方法
}

3. 定义座位类

public class Seat {
    private String seatNumber;
    private boolean isAvailable;
    // 省略构造函数和getter/setter方法
}

4. 定义订票类

public class Booking {
    private Flight flight;
    private Passenger passenger;
    private Seat seat;
    // 省略构造函数和getter/setter方法
}

然后，我们需要实现一些基本的功能，如查询航班、预订座位等。以下是一个简单的代码示例：

1. 查询航班

public class FlightService {
    private List<Flight> flights;
    
    public FlightService() {
        // 初始化航班数据
        flights = new ArrayList<>();
        flights.add(new Flight("CA001", "北京", "上海", new Date(), new Date(), 100));
        flights.add(new Flight("CA002", "上海", "北京", new Date(), new Date(), 100));
    }
    
    public List<Flight> searchFlights(String departureCity, String arrivalCity) {
        List<Flight> result = new ArrayList<>();
        for (Flight flight : flights) {
            if (flight.getDepartureCity().equals(departureCity) && flight.getArrivalCity().equals(arrivalCity)) {
                result.add(flight);
            }
        }
        return result;
    }
}

2. 预订座位

public class SeatService {
    private Map<Flight, List<Seat>> seats;
    
    public SeatService() {
        // 初始化座位数据
        seats = new HashMap<>();
        for (Flight flight : flights) {
            List<Seat> seatList = new ArrayList<>();
            for (int i = 1; i <= flight.getAvailableSeats(); i++) {
                seatList.add(new Seat(String.valueOf(i), true));
            }
            seats.put(flight, seatList);
        }
    }
    
    public Seat bookSeat(Flight flight, Passenger passenger) throws Exception {
        List<Seat> seatList = seats.get(flight);
        for (Seat seat : seatList) {
            if (seat.isAvailable()) {
                seat.setAvailable(false);
                return seat;
            }
        }
        throw new Exception("No available seat for flight " + flight.getFlightNumber());
    }
}

这只是一个简单的示例，实际的系统可能需要更复杂的功能和更多的实体类。希望这个示例能为您提供一些帮助。
