发布一个酒店管理系统代码，用javase数组等知识实现的

一个酒店管理系统要做到的基础操作有哪些？

1.房间状态的查询

2.预定入住

3.退房

4.及时更改酒店房间的信息

在这里我通过三个类实现的，一个房间类，一个方法类，一个测试类

房间类

package com.lh1029.hotel;

public class Room {
 
 //房间的编号  
 private String id;
 //房间的类型
 private String type; 
 //房间是否以使用
 private boolean isUse;

//一下代码都可以通过编译器生成，所以简单

public String getId() {
  return id;
 }
 public void setId(String id) {
  this.id = id;
 }
 public String getType() {
  return type;
  }
public void setType(String type) {
  this.type = type;
 }
 public boolean isUse() {
  return isUse;
 }
 public void setUse(boolean isUse) {
  this.isUse = isUse;
 }

@Override 
 public String toString() {
  return "[" + id + "," + type + "," + (isUse?"occupy":"leisure")+"]";
 }
 
public Room(String i, String type, boolean isUse) {
 
  this.id = i;
  this.type = type;
  this.isUse = isUse;
 }
 //构造方法
 public Room() {

}

酒店类

package com.lh1029.hotel;

public class Hotel {
public Hotel() {
//创建room类，共60间房
  room = new Room[6][10];
  
  for(int i=0;i<room.length;i++){
   for(int j=0;j<room[i].length;j++){
    if(i==0||i==1){
     room[i][j]=new Room((i+1)*100+j+1+"","Standard Room",false);
    }
    if(i==2||i==3) {
     room[i][j]=new Room((i+1)*100+j+1+"","double room",false);        
    }
    if(i==4||i==5) {
     room[i][j]=new Room((i+1)*100+j+1+"","deluxe room ",false);
    }
   }
  }
 }

//打印房间列表状态
 public void print(){
  for(int i=0;i<room.length;i++){
   for(int j=0;j<room[i].length;j++){
    System.out.print(room[i][j]+" ");
   }
   System.out.println();
  }
 }

//入住
 public void order(String id) {
  for(int i=0;i<room.length;i++){
   for(int j=0;j<room[i].length;j++) {
    if(room[i][j].getId().equals(id)) {
     room[i][j].setUse(true);
    }
   }
  }
 }

//退房
 public void checkOut(String id) {
  for(int i=0;i<room.length;i++){
   for(int j=0;j<room[i].length;j++) {
    if(room[i][j].getId().equals(id)) {
     room[i][j].setUse(false);
    }
   }
  }
 }
 }

测试类

package com.lh1029.hotel;

import java.util.Scanner;

public class Test {
 private static Scanner s;

 public static void main(String[] args) {
  s = new Scanner(System.in);
  System.out.println("Welcome to the hotel management system");
  //创建一个酒店类
  Hotel h=new Hotel();
  //打印创建的房间列表
  h.print();
  //进入循环,订房/退房<->订房/退房
  while(true) {
  System.out.println("Please enter check-out or reservation");
  //输入是退房还是订房，下面进行判断
  String order =s.next();
  if("reservation".equals(order)) {
   System.out.println("Please enter the room number");
   String id =s.next();
   //输入入住id
   h.order(id);
   }else if("check-out".equals(order)) {
   System.out.println("Please enter the room number");
   String id =s.next();
   //输入退房id
   h.checkOut(id);
   }else {
   System.out.println("Please enter the room number");
  }
  //及时更新房间列表信息
  h.print();
  }
 }
 }//这里肯定不是最漂亮的代码，比较基础
