java的酒店管理系统代码举例

这里提供一个简单的酒店管理系统的Java代码示例，包括客房管理和客户管理功能。

Room类：

public class Room {
    private int roomNumber;
    private String roomType;
    private boolean isAvailable;
    private double roomRate;
    
    public Room(int number, String type, double rate) {
        this.roomNumber = number;
        this.roomType = type;
        this.isAvailable = true;
        this.roomRate = rate;
    }
    
    public int getRoomNumber() {
        return roomNumber;
    }
    
    public String getRoomType() {
        return roomType;
    }
    
    public boolean isAvailable() {
        return isAvailable;
    }
    
    public double getRoomRate() {
        return roomRate;
    }
    
    public void bookRoom() {
        isAvailable = false;
    }
    
    public void checkoutRoom() {
        isAvailable = true;
    }
}

Customer类：

public class Customer {
    private String name;
    private String address;
    private String phone;
    private int roomNumber;
    private int nights;
    
    public Customer(String name, String address, String phone) {
        this.name = name;
        this.address = address;
        this.phone = phone;
    }
    
    public String getName() {
        return name;
    }
    
    public String getAddress() {
        return address;
    }
    
    public String getPhone() {
        return phone;
    }
    
    public int getRoomNumber() {
        return roomNumber;
    }
    
    public void setRoomNumber(int roomNumber) {
        this.roomNumber = roomNumber;
    }
    
    public int getNights() {
        return nights;
    }
    
    public void setNights(int nights) {
        this.nights = nights;
    }
}

Hotel类：

import java.util.ArrayList;

public class Hotel {
    private ArrayList<Room> rooms;
    private ArrayList<Customer> customers;
    
    public Hotel() {
        rooms = new ArrayList<Room>();
        customers = new ArrayList<Customer>();
    }
    
    public void addRoom(Room room) {
        rooms.add(room);
    }
    
    public void addCustomer(Customer customer) {
        customers.add(customer);
    }
    
    public boolean bookRoom(int roomNumber, Customer customer, int nights) {
        for (Room room : rooms) {
            if (room.getRoomNumber() == roomNumber && room.isAvailable()) {
                room.bookRoom();
                customer.setRoomNumber(roomNumber);
                customer.setNights(nights);
                customers.add(customer);
                return true;
            }
        }
        return false;
    }
    
    public double checkoutCustomer(Customer customer) {
        for (Customer c : customers) {
            if (c.equals(customer)) {
                for (Room room : rooms) {
                    if (room.getRoomNumber() == customer.getRoomNumber()) {
                        room.checkoutRoom();
                        customers.remove(customer);
                        return room.getRoomRate() * customer.getNights();
                    }
                }
            }
        }
        return -1;
    }
}

上述代码实现了客房管理和客户管理的基本功能，可以根据实际需求进行修改和扩展。
