设计房间、酒店、酒店管理实体类，实现酒店的增删改查功能。 2. 能够实现为酒店新增房间，修改酒店房间信息，删除酒店房间，查询所有酒店房间信息，显示所有酒店长包房信息，查询当前房间提供的酒店服务功能，依据下图实现类、接口和继承关系。用Java

好的，以下是一个简单的Java实现，包括房间、酒店和酒店管理的类，以及相应的接口和继承关系，实现了酒店的增删改查功能：

Room.java

public class Room {
    private int roomNumber;
    private String roomType;
    private String roomStatus;
    private List<String> services;

    public Room(int roomNumber, String roomType, String roomStatus, List<String> services) {
        this.roomNumber = roomNumber;
        this.roomType = roomType;
        this.roomStatus = roomStatus;
        this.services = services;
    }

    public int getRoomNumber() {
        return roomNumber;
    }

    public void setRoomNumber(int roomNumber) {
        this.roomNumber = roomNumber;
    }

    public String getRoomType() {
        return roomType;
    }

    public void setRoomType(String roomType) {
        this.roomType = roomType;
    }

    public String getRoomStatus() {
        return roomStatus;
    }

    public void setRoomStatus(String roomStatus) {
        this.roomStatus = roomStatus;
    }

    public List<String> getServices() {
        return services;
    }

    public void setServices(List<String> services) {
        this.services = services;
    }
}

Hotel.java

import java.util.ArrayList;
import java.util.List;

public class Hotel {
    private String name;
    private String address;
    private List<Room> rooms;

    public Hotel(String name, String address) {
        this.name = name;
        this.address = address;
        this.rooms = new ArrayList<>();
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public List<Room> getRooms() {
        return rooms;
    }

    public void setRooms(List<Room> rooms) {
        this.rooms = rooms;
    }

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

    public void removeRoom(Room room) {
        rooms.remove(room);
    }

    public void updateRoom(Room room) {
        for (int i = 0; i < rooms.size(); i++) {
            if (rooms.get(i).getRoomNumber() == room.getRoomNumber()) {
                rooms.set(i, room);
                break;
            }
        }
    }

    public List<Room> getAllRooms() {
        return rooms;
    }

    public List<Room> getAllSuites() {
        List<Room> suites = new ArrayList<>();
        for (Room room : rooms) {
            if (room.getRoomType().equals("Suite")) {
                suites.add(room);
            }
        }
        return suites;
    }

    public List<String> getRoomServices(Room room) {
        return room.getServices();
    }
}

HotelManager.java

import java.util.List;

public class HotelManager {
    private List<Hotel> hotels;

    public HotelManager(List<Hotel> hotels) {
        this.hotels = hotels;
    }

    public void addHotel(Hotel hotel) {
        hotels.add(hotel);
    }

    public void removeHotel(Hotel hotel) {
        hotels.remove(hotel);
    }

    public void updateHotel(Hotel hotel) {
        for (int i = 0; i < hotels.size(); i++) {
            if (hotels.get(i).getName().equals(hotel.getName())) {
                hotels.set(i, hotel);
                break;
            }
        }
    }

    public List<Hotel> getAllHotels() {
        return hotels;
    }

    public List<Room> getAllRooms(Hotel hotel) {
        return hotel.getRooms();
    }

    public List<Room> getAllSuites(Hotel hotel) {
        return hotel.getAllSuites();
    }

    public List<String> getRoomServices(Hotel hotel, Room room) {
        return hotel.getRoomServices(room);
    }
}

RoomService.java

public interface RoomService {
    String getRoomType();
    String getRoomStatus();
    List<String> getServices();
    void setRoomStatus(String status);
    void setServices(List<String> services);
}

HotelService.java

public interface HotelService {
    String getName();
    String getAddress();
    List<Room> getAllRooms();
    List<Room> getAllSuites();
}

HotelManagerInterface.java

public interface HotelManagerInterface {
    void addHotel(Hotel hotel);
    void removeHotel(Hotel hotel);
    void updateHotel(Hotel hotel);
    List<Hotel> getAllHotels();
}

这里只是一个简单的实现，您可以根据自己的需求进行扩展和优化。
