酒店管理系统java实现

酒店管理系统是一种常见的管理信息系统，它可以帮助酒店管理者进行酒店的日常运营管理。下面是一个简单的酒店管理系统java实现的示例：

1. 酒店房间类Room.java

public class Room {
    private int roomId;
    private String roomType;
    private String roomStatus;
    private double roomPrice;

    public Room(int roomId, String roomType, String roomStatus, double roomPrice) {
        this.roomId = roomId;
        this.roomType = roomType;
        this.roomStatus = roomStatus;
        this.roomPrice = roomPrice;
    }

    public int getRoomId() {
        return roomId;
    }

    public void setRoomId(int roomId) {
        this.roomId = roomId;
    }

    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 double getRoomPrice() {
        return roomPrice;
    }

    public void setRoomPrice(double roomPrice) {
        this.roomPrice = roomPrice;
    }
}

2. 酒店管理类Hotel.java

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

public class Hotel {
    private List<Room> rooms = new ArrayList<>();

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

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

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

    public List<Room> getAvailableRooms() {
        List<Room> availableRooms = new ArrayList<>();
        for (Room room : rooms) {
            if (room.getRoomStatus().equals("available")) {
                availableRooms.add(room);
            }
        }
        return availableRooms;
    }

    public List<Room> getOccupiedRooms() {
        List<Room> occupiedRooms = new ArrayList<>();
        for (Room room : rooms) {
            if (room.getRoomStatus().equals("occupied")) {
                occupiedRooms.add(room);
            }
        }
        return occupiedRooms;
    }

    public List<Room> getRoomsByType(String roomType) {
        List<Room> roomsByType = new ArrayList<>();
        for (Room room : rooms) {
            if (room.getRoomType().equals(roomType)) {
                roomsByType.add(room);
            }
        }
        return roomsByType;
    }

    public double getOccupancyRate() {
        int totalRooms = rooms.size();
        int occupiedRooms = getOccupiedRooms().size();
        return (double)occupiedRooms / totalRooms;
    }

    public double getAverageRoomPrice() {
        double totalRoomPrice = 0;
        for (Room room : rooms) {
            totalRoomPrice += room.getRoomPrice();
        }
        return totalRoomPrice / rooms.size();
    }
}

3. 酒店管理系统主程序HotelManagementSystem.java

import java.util.List;
import java.util.Scanner;

public class HotelManagementSystem {
    public static void main(String[] args) {
        Hotel hotel = new Hotel();

        // 添加房间
        Room room1 = new Room(101, "single", "available", 100);
        Room room2 = new Room(102, "double", "available", 200);
        Room room3 = new Room(103, "single", "occupied", 100);
        hotel.addRoom(room1);
        hotel.addRoom(room2);
        hotel.addRoom(room3);

        Scanner scanner = new Scanner(System.in);

        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 查询所有房间信息");
            System.out.println("2. 查询空闲房间信息");
            System.out.println("3. 查询已入住房间信息");
            System.out.println("4. 查询指定类型房间信息");
            System.out.println("5. 查询酒店入住率");
            System.out.println("6. 查询酒店平均房价");
            System.out.println("7. 退出系统");
            String option = scanner.next();

            switch (option) {
                case "1":
                    List<Room> rooms = hotel.getRooms();
                    System.out.println("所有房间信息：");
                    for (Room room : rooms) {
                        System.out.println(room.getRoomId() + " " + room.getRoomType() + " " + room.getRoomStatus() + " " + room.getRoomPrice());
                    }
                    break;
                case "2":
                    List<Room> availableRooms = hotel.getAvailableRooms();
                    System.out.println("空闲房间信息：");
                    for (Room room : availableRooms) {
                        System.out.println(room.getRoomId() + " " + room.getRoomType() + " " + room.getRoomStatus() + " " + room.getRoomPrice());
                    }
                    break;
                case "3":
                    List<Room> occupiedRooms = hotel.getOccupiedRooms();
                    System.out.println("已入住房间信息：");
                    for (Room room : occupiedRooms) {
                        System.out.println(room.getRoomId() + " " + room.getRoomType() + " " + room.getRoomStatus() + " " + room.getRoomPrice());
                    }
                    break;
                case "4":
                    System.out.println("请输入房间类型：");
                    String roomType = scanner.next();
                    List<Room> roomsByType = hotel.getRoomsByType(roomType);
                    System.out.println("指定类型房间信息：");
                    for (Room room : roomsByType) {
                        System.out.println(room.getRoomId() + " " + room.getRoomType() + " " + room.getRoomStatus() + " " + room.getRoomPrice());
                    }
                    break;
                case "5":
                    double occupancyRate = hotel.getOccupancyRate();
                    System.out.println("酒店入住率：" + occupancyRate);
                    break;
                case "6":
                    double averageRoomPrice = hotel.getAverageRoomPrice();
                    System.out.println("酒店平均房价：" + averageRoomPrice);
                    break;
                case "7":
                    System.exit(0);
                    break;
                default:
                    System.out.println("无效操作，请重新选择！");
                    break;
            }
        }
    }
}

以上是一个简单的酒店管理系统java实现的示例，可以根据实际需要进一步扩展和完善。
