酒店管理系统是一款功能强大、操作简便的酒店管理软件,是酒店进行前台管理、电话预定管理、收银管理、统计查询管理、会员管理、房卡管理、库存管理、报表管理、经理查询、系统维护等的必备工具。要实现这样的系统需要费些功夫,通过java实现简单的功能。
思路:
共有5层,每层10间客房,以数字101--509标示;
具有入住,退房,搜索,退出四个简单功能;
public class Hotel {
static final int floor = 5;
static final int order = 10;
private static int countFloor;
private static int countOrder;
private static String[][] rooms = new String[floor][order];
//main函数代表酒店的基本功能,入住,退房,查询,其他;
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String temp = null;
while(true){
//提醒用户选择输入
System.out.println("请选择输入 in out search quit : ");
temp = scan.next();
int room = 0;
if("in".equals(temp)){
while(true){
System.out.println("请输入房间号:");
room = scan.nextInt();
if(isRightRoom(room,1)){
break;
}
}
System.out.println("请输入名字:");
String name = scan.next();
if(in(room,name)){
System.out.println("恭喜您,入住成功");
System.out.println(room + " : "+name);
}
}else if("out".equals(temp)){
while(true){
System.out.println("请输入房间号:");
room = scan.nextInt();
if(isRightRoom(room,0)){
break;
}
}
if(out(room)){
System.out.println("退房成功,欢迎下次光临");
}
}else if("search".equals(temp)){
System.out.println("请输入查询的房间号(-1表示全部)");
room = scan.nextInt();
search(room);
}else if("quit".equals(temp)){
break;
}else{
System.out.println("您的输入有误,请再次输入!");
}
}
}
//flag:1 检查房间号输入正确 且 无人入住 0 仅检查房间号输入正确
private static boolean isRightRoom(int room,int flag) {
//校验房间号是否输入有误
countFloor = room / 100 - 1;
countOrder = room % 100 - 1;
if(countFloor < 0 || countFloor >= floor || countOrder < 0 || countOrder >= order ){
System.out.println("输入的房间号有误");
return false;
}
if(flag == 1){
if(rooms[countFloor][countOrder] != null){
System.out.println("房间已经入住");
return false;
}
}
return true;
}
//旅馆入住功能实现,in(room,name) countFloor:计算出的楼层 countOrder:计算出的房间顺序
private static boolean in(int room,String name){
rooms[countFloor][countOrder] = name;
return true;
}
//旅馆退房功能实现,out(room),
private static boolean out(int room){
//校验房间号是否有人入住
if(rooms[countFloor][countOrder] == null){
System.out.println("房间未曾入住,退房有误");
return false;
}
rooms[countFloor][countOrder] = null;
return true;
}
//旅馆搜索功能,search(room)
private static void search(int room){
if(room == -1){
int roomNum = 0;
for(int i=0;i<floor;i++){
for(int j=0;j<order;j++){
roomNum = (i + 1) * 100 + j + 1;
System.out.println(roomNum + "->" +
(rooms[i][j] == null ? "empty" : rooms[i][j]));
}
}
}else{
//校验房间号是否正确
if(!isRightRoom(room,0)){
System.out.println("抱歉,房间输入错误!");
}else{
System.out.println(rooms[countFloor][countOrder]);
}
}
}}
