酒店管理系統(tǒng)數(shù)據(jù)統(tǒng)計模塊怎么做？大神求指點（java）

找個簡單的：

讓客戶滿意是我們工作的目標，不斷超越客戶的期望值來自于我們對這個行業(yè)的熱愛。我們立志把好的技術(shù)通過有效、簡單的方式提供給客戶，將通過不懈努力成為客戶在信息化領(lǐng)域值得信任、有價值的長期合作伙伴，公司提供的服務(wù)項目有：域名與空間、網(wǎng)頁空間、營銷軟件、網(wǎng)站建設(shè)、同仁網(wǎng)站維護、網(wǎng)站推廣。

import?java.util.Scanner;

public?class?a1{

public?static?void?main(String[]?args){

Scanner?s?=?new?Scanner(System.in);//接受客戶鍵盤輸入，在命令行中，回車結(jié)束

System.out.println(?"酒店管理系統(tǒng)"?);

Hotel?h?=?new?Hotel();

System.out.println(?h?);

h.print();

while?(true){

System.out.println(?"請輸入房間編號"?);

//聲明變量,用于接受控制臺輸入數(shù)據(jù)

String?no?=?s.next();

//預(yù)訂房間

h.order(no);

h.print();

}

}

}

class?Room{

//房間號

private?String?no;

//房間類型

private?String?type;

//是否被占用

private?boolean?isUse;

public?Room(){//默認調(diào)用

super();

}

public?Room(String?no,String?type,boolean?isUse){

super();

this.no?=?no;

this.type?=?type;

this.isUse?=?isUse;

}

public?String?getNo(){

}

}

}

}

public?boolean?isUse(){

return?isUse;

}

public?void?setUse(boolean?isUse){

this.isUse?=?isUse;

}

public?String?toString(){??//聲明輸出結(jié)果格式

return?"["?+?no?+?","?+?type?+?","?+?(isUse?"占用":"空閑")?+?"]";

}

}

class?Hotel{

Room?rooms[][];

public?Hotel(){

rooms?=?new?Room[5][4];//旅館有五層，每層四個房間

for(int?i=0;?i??rooms.length;?++i){//外層for循環(huán)是循環(huán)層,內(nèi)存循環(huán)是循環(huán)的每層的房間

for(int?j=0;?j??rooms[i].length;?++j){

if?(i?==?0?||?i?==?1)?{

//后面加個空字符串,是自動數(shù)據(jù)類型轉(zhuǎn)換,這樣前面的數(shù)字會自動變成數(shù)字型字符串;

rooms[i][j]?=?new?Room((i+1)*100+j+1?+""?,?"標準間",false);

}

if?(i?==?2?||?i?==?3)?{

rooms[i][j]?=?new?Room((i+1)*100+j+1?+""?,?"雙人間",false);?

}

if?(i?==?4)?{

rooms[i][j]?=?new?Room((i+1)*100+j+1?+""?,?"豪華間",false);?

}

}

}

}

//對外提供房間列表的打印方式

public?void?print(){

for(int?i=0;?i??rooms.length;?++i){

for(int?j=0;?j??rooms[i].length;?++j){

System.out.print(?rooms[i][j]?+?"?"?);

}

//換行

System.out.println(??);

}

}

//提供旅館對外預(yù)定方式

public?void?order(String?no){

for(int?i=0;?i??rooms.length;?++i){

for(int?j=0;?j??rooms[i].length;?++j){

if?(rooms[i][j].getNo().equals(no))?{

//把對象的成員數(shù)據(jù)封裝,通過成員方法訪問

//1?成員變量的訪問方式rooms[i][j].no;

//2?成員方法的訪問方式

rooms[i][j].setUse(true);

return;

}

}

}

}

}

帶數(shù)據(jù)庫的就算了

java面試題：酒店預(yù)訂！

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("是否是會員？y/n");

String H = input.next();

System.out.println("請輸入入住日期：");

System.out.println("例如2009-03-16");

System.out.println("請輸離開日期：");

System.out.println("例如2009-03-16");

String out = input.next();

//String in = s.substring(5,15);

//String out = s.substring(15,26);

//System.out.println(in+" "+out);

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

Calendar c1 = Calendar.getInstance();

Calendar c2 = Calendar.getInstance();

try {

c1.setTime(sdf.parse(in));

c2.setTime(sdf.parse(out));

} catch (ParseException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

long time1 = c1.getTimeInMillis();

long time2 = c2.getTimeInMillis();

long tian = (time2-time1)/(1000*24*3600);

long tian1 = tian;

System.out.println("tian "+tian);

int week1 = c1.get(Calendar.DAY_OF_WEEK)-1;

int count = 0;

while(tian10){

if(week1 == 6 || week1==0){

count++;

}

if(week1==6){

week1 = 0;

week1--;

}

tian1--;

week1++;

}

System.out.println("count "+count);

long rujia;

if(H.equals("y")){

rujia = (tian-count)*80+count*80;

System.out.println("tian "+tian);

}

我沒怎么測試 自己測測吧 還有一些約束用戶輸入啥的 嚴謹性什么的
