链表java实现飞机票管理系统

链表可以用于实现飞机票管理系统的航班信息存储和操作。下面是一个简单的Java代码示例，演示了如何使用链表实现航班信息的添加、删除和查询功能：

import java.util.LinkedList;

// 定义航班类
class Flight {
    private String flightNumber;
    private String departure;
    private String destination;
    private String departureTime;
    private String arrivalTime;

    // 构造函数
    public Flight(String flightNumber, String departure, String destination, String departureTime, String arrivalTime) {
        this.flightNumber = flightNumber;
        this.departure = departure;
        this.destination = destination;
        this.departureTime = departureTime;
        this.arrivalTime = arrivalTime;
    }

    // getter和setter方法
    // ...

    // toString方法
    @Override
    public String toString() {
        return "Flight{" +
                "flightNumber='" + flightNumber + '\'' +
                ", departure='" + departure + '\'' +
                ", destination='" + destination + '\'' +
                ", departureTime='" + departureTime + '\'' +
                ", arrivalTime='" + arrivalTime + '\'' +
                '}';
    }
}

// 航班信息管理系统类
class FlightManagementSystem {
    private LinkedList<Flight> flights;

    // 构造函数
    public FlightManagementSystem() {
        flights = new LinkedList<>();
    }

    // 添加航班信息
    public void addFlight(Flight flight) {
        flights.add(flight);
    }

    // 删除航班信息
    public void deleteFlight(Flight flight) {
        flights.remove(flight);
    }

    // 根据航班号查询航班信息
    public Flight searchFlightByNumber(String flightNumber) {
        for (Flight flight : flights) {
            if (flight.getFlightNumber().equals(flightNumber)) {
                return flight;
            }
        }
        return null;
    }

    // 查询所有航班信息
    public LinkedList<Flight> getAllFlights() {
        return flights;
    }
}

// 测试代码
public class Main {
    public static void main(String[] args) {
        // 创建航班信息管理系统对象
        FlightManagementSystem system = new FlightManagementSystem();

        // 添加航班信息
        Flight flight1 = new Flight("CA123", "Beijing", "Shanghai", "08:00", "10:00");
        Flight flight2 = new Flight("MU456", "Shanghai", "Guangzhou", "12:00", "14:00");
        system.addFlight(flight1);
        system.addFlight(flight2);

        // 查询航班信息
        Flight searchResult = system.searchFlightByNumber("CA123");
        System.out.println("查询结果：" + searchResult);

        // 删除航班信息
        system.deleteFlight(flight2);

        // 查询所有航班信息
        LinkedList<Flight> allFlights = system.getAllFlights();
        System.out.println("所有航班信息：");
        for (Flight flight : allFlights) {
            System.out.println(flight);
        }
    }
}
