酒店管理系统的Java设计

酒店管理系统的Java设计可以包含以下几个主要模块：用户管理、房间管理、订单管理和报表统计。下面是一个简单的示例代码，用于说明这些模块的设计和实现。

1. 用户管理模块：

public class User {
    private String username;
    private String password;
    // 其他用户信息...

    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }

    // getter和setter方法...
}

public class UserManager {
    private List<User> userList;

    public UserManager() {
        this.userList = new ArrayList<>();
    }

    public void addUser(User user) {
        userList.add(user);
    }

    public boolean authenticateUser(String username, String password) {
        for (User user : userList) {
            if (user.getUsername().equals(username) && user.getPassword().equals(password)) {
                return true;
            }
        }
        return false;
    }
    // 其他用户管理功能...
}

2. 房间管理模块：

public class Room {
    private int roomNumber;
    private boolean isOccupied;
    // 其他房间信息...

    public Room(int roomNumber) {
        this.roomNumber = roomNumber;
        this.isOccupied = false;
    }

    // getter和setter方法...
}

public class RoomManager {
    private List<Room> roomList;

    public RoomManager() {
        this.roomList = new ArrayList<>();
    }

    public void addRoom(Room room) {
        roomList.add(room);
    }

    public Room getAvailableRoom() {
        for (Room room : roomList) {
            if (!room.isOccupied()) {
                return room;
            }
        }
        return null;
    }
    // 其他房间管理功能...
}

3. 订单管理模块：

public class Order {
    private User user;
    private Room room;
    private Date checkInDate;
    private Date checkOutDate;
    // 其他订单信息...

    public Order(User user, Room room, Date checkInDate, Date checkOutDate) {
        this.user = user;
        this.room = room;
        this.checkInDate = checkInDate;
        this.checkOutDate = checkOutDate;
    }

    // getter和setter方法...
}

public class OrderManager {
    private List<Order> orderList;

    public OrderManager() {
        this.orderList = new ArrayList<>();
    }

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

    public List<Order> getUserOrders(User user) {
        List<Order> userOrders = new ArrayList<>();
        for (Order order : orderList) {
            if (order.getUser().equals(user)) {
                userOrders.add(order);
            }
        }
        return userOrders;
    }
    // 其他订单管理功能...
}

4. 报表统计模块：

public class ReportManager {
    private OrderManager orderManager;

    public ReportManager(OrderManager orderManager) {
        this.orderManager = orderManager;
    }

    public int getTotalOrders() {
        return orderManager.getOrderList().size();
    }

    public int getOccupiedRooms() {
        int count = 0;
        for (Order order : orderManager.getOrderList()) {
            if (order.getRoom().isOccupied()) {
                count++;
            }
        }
        return count;
    }
    // 其他报表统计功能...
}

以上代码只是一个简单的示例，实际的酒店管理系统可能需要更多的功能和复杂的实现。这里的重点是展示一个基本的设计和代码示例，供参考和学习。
