用java写一个物流管理系统

下面是一个简单的Java物流管理系统的示例代码：

// 物流管理系统主类
public class LogisticsManagementSystem {
    private List<Order> orders;
    private List<Driver> drivers;
    private List<Delivery> deliveries;

    public LogisticsManagementSystem() {
        this.orders = new ArrayList<>();
        this.drivers = new ArrayList<>();
        this.deliveries = new ArrayList<>();
    }

    public void addOrder(Order order) {
        orders.add(order);
    }

    public void addDriver(Driver driver) {
        drivers.add(driver);
    }

    public void assignDelivery(Order order, Driver driver) {
        Delivery delivery = new Delivery(order, driver);
        deliveries.add(delivery);
    }

    public List<Delivery> getDeliveries() {
        return deliveries;
    }
}

// 订单类
public class Order {
    private String orderId;
    private String customerName;
    private String address;

    public Order(String orderId, String customerName, String address) {
        this.orderId = orderId;
        this.customerName = customerName;
        this.address = address;
    }

    // getters and setters
}

// 司机类
public class Driver {
    private String driverId;
    private String driverName;
    private String vehicleNumber;

    public Driver(String driverId, String driverName, String vehicleNumber) {
        this.driverId = driverId;
        this.driverName = driverName;
        this.vehicleNumber = vehicleNumber;
    }

    // getters and setters
}

// 配送类
public class Delivery {
    private Order order;
    private Driver driver;
    private LocalDateTime deliveryTime;

    public Delivery(Order order, Driver driver) {
        this.order = order;
        this.driver = driver;
        this.deliveryTime = LocalDateTime.now();
    }

    // getters and setters
}

// 示例用法
public class Main {
    public static void main(String[] args) {
        LogisticsManagementSystem system = new LogisticsManagementSystem();

        // 添加订单
        Order order1 = new Order("1001", "John Doe", "123 Main St");
        system.addOrder(order1);

        Order order2 = new Order("1002", "Jane Smith", "456 Elm St");
        system.addOrder(order2);

        // 添加司机
        Driver driver1 = new Driver("D001", "Tom", "ABC123");
        system.addDriver(driver1);

        Driver driver2 = new Driver("D002", "Jerry", "DEF456");
        system.addDriver(driver2);

        // 分配配送
        system.assignDelivery(order1, driver1);
        system.assignDelivery(order2, driver2);

        // 获取所有配送信息
        List<Delivery> deliveries = system.getDeliveries();
        for (Delivery delivery : deliveries) {
            System.out.println("Delivery for Order " + delivery.getOrder().getOrderId() +
                    " assigned to Driver " + delivery.getDriver().getDriverId() +
                    " at " + delivery.getDeliveryTime());
        }
    }
}

这只是一个简单的物流管理系统示例，你可以根据实际需求进行扩展和修改。这个示例包含了订单、司机、配送等类，通过主类中的方法进行订单的添加、司机的添加以及配送的分配，并最后获取所有的配送信息进行输出。你可以根据实际情况进行修改和扩展。
