Java数据结构航空客运订票系统代码

Java数据结构航空客运订票系统代码是一个用Java语言编写的航空客运订票系统的代码实现。该系统使用了多种数据结构来管理航班信息、乘客信息和座位信息等。

以下是一个简单的Java数据结构航空客运订票系统代码示例：

import java.util.HashMap;
import java.util.Map;

public class AirlineTicketSystem {
    private Map<String, Flight> flights;

    public AirlineTicketSystem() {
        flights = new HashMap<>();
    }

    public void addFlight(String flightNumber, String departure, String destination, int capacity) {
        Flight flight = new Flight(flightNumber, departure, destination, capacity);
        flights.put(flightNumber, flight);
    }

    public void bookTicket(String flightNumber, String passengerName) {
        Flight flight = flights.get(flightNumber);
        if (flight != null) {
            if (flight.hasAvailableSeats()) {
                flight.bookSeat(passengerName);
                System.out.println("Ticket booked successfully.");
            } else {
                System.out.println("No available seats on this flight.");
            }
        } else {
            System.out.println("Flight not found.");
        }
    }

    public void displayFlightDetails(String flightNumber) {
        Flight flight = flights.get(flightNumber);
        if (flight != null) {
            System.out.println("Flight Number: " + flight.getFlightNumber());
            System.out.println("Departure: " + flight.getDeparture());
            System.out.println("Destination: " + flight.getDestination());
            System.out.println("Available Seats: " + flight.getAvailableSeats());
        } else {
            System.out.println("Flight not found.");
        }
    }

    private class Flight {
        private String flightNumber;
        private String departure;
        private String destination;
        private int capacity;
        private int bookedSeats;

        public Flight(String flightNumber, String departure, String destination, int capacity) {
            this.flightNumber = flightNumber;
            this.departure = departure;
            this.destination = destination;
            this.capacity = capacity;
            this.bookedSeats = 0;
        }

        public String getFlightNumber() {
            return flightNumber;
        }

        public String getDeparture() {
            return departure;
        }

        public String getDestination() {
            return destination;
        }

        public int getAvailableSeats() {
            return capacity - bookedSeats;
        }

        public boolean hasAvailableSeats() {
            return bookedSeats < capacity;
        }

        public void bookSeat(String passengerName) {
            bookedSeats++;
            System.out.println("Seat booked for passenger: " + passengerName);
        }
    }
}

这段代码实现了一个简单的航空客运订票系统，其中包含了航班信息的添加、乘客订票和显示航班详情等功能。航班信息使用Flight类来表示，每个Flight对象包含航班号、出发地、目的地、座位容量和已预订座位数等属性。航班信息存储在AirlineTicketSystem类中的flights变量中，使用HashMap来进行快速查找。
