Java课程作业，酒店管理系统由前台系统实现主要功能，具备以下功能：
目录
Room
Customer
CheckList
Hotel
HotelSystem
Room
Room类，包含了房间号，房间类型，房间状态（住宿还是空闲），房间价格，以及入住人信息。
//Room 类
import java.util.Objects;
public class Room{
private int roomnumber;
public String type;
private int status;//房间状态，1：入住；0：空闲；-1：被预订
private int price;
public Customer customerInfo = new Customer();
public Room() {
}
public Room(int roomnumber, String type, int status,int price) {
this.roomnumber = roomnumber;
this.type = type;
this.status = status;
this.price = price ;
}
public int getRoomnumber() {return roomnumber;}
public void setRoomnumber(int roomnumber) {this.roomnumber = roomnumber;}
public String getType() {return type;}
public void setType(String type) {this.type = type;}
public int getStatus() {return status;}
public void setStatus(int status) {this.status = status;}
public int getPrice() {return price;}
public void setPrice(int price) {this.price = price;}
//重写toString方法，可以转换成输出房间信息
@Override
public String toString() {
String roominfo = new String();
switch(status)
{
case 0 :
roominfo = "ROOM信息{"+roomnumber+","+type+","+"空闲"+"}";
break;
case 1:
roominfo = "ROOM信息{"+roomnumber+","+type+","+"已满"+"}";
break;
case -1:
roominfo = "ROOM信息{"+roomnumber+","+type+","+"已预订"+"}";
break;
}
return roominfo;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Room room = (Room) o;
return roomnumber== room.roomnumber && status == room.status && Objects.equals(type, room.type);
}
public int hashCode() {
return Objects.hash(roomnumber, status, type,price);
}
}
Customer
Customer类，用于实现顾客属性。
public class Customer {
public String cname;
public int age;
public String cid;
public String phone;
public int pay;
public int getPay() {return pay;}
public void setPay(int pay) {this.pay = pay;}
public int getAge() {return age;}
public void setAge(int age) {this.age = age;}
public String getName() {return cname;}
public void setName(String name) {this.cname = name;}
public String getPhone() {return phone;}
public void setPhone(String phone) {this.phone = phone;}
public String getId() {return cid;}
public void setId(String id) {this.cid = id;}
public void customer(String customerName, int customerAge, String customerId, String customerphone)
{
this.cname = customerName;
this.age = customerAge;
this.cid = customerId;
this.phone = customerphone;
}
}
CheckList
这个是老师让改的一部分，对于查询记录的类
//记录类
public class CheckList
{
private Room room;
public Date startTime;
public CheckList(Room room,Date startTime)
{
this.room = room;
this.startTime =startTime;
}
public Room getRoom()
{
return room;
}
public void setRoom(Room room)
{
this.room = room;
}
public Date getStartTime()
{
return startTime;
}
public void setStartTime(Date startTime)
{
this.startTime = startTime;
}
}
//入住记录类
class CheckInList extends CheckList
{
public CheckInList(Room room, Date startTime) {
super(room, startTime);
}
}
//历史记录类
class CheckOutList extends CheckList
{
public Date endTime;
public CheckOutList(Room room,Date startTime,Date endTime)
{
super(room,startTime);
this.endTime = endTime;
}
public Date getEndTime()
{
return startTime;
}
public void setEndTime(Date endTime)
{
this.endTime = endTime;
}
}Hotel
