this.hotelPhone = hotelPhone;

}

private String hotelPhone;

}

客户类

酒店管理系统数据统计模块怎么做？大神求指点（java）

找个简单的：

import java.util.Scanner;

public class a1{

public static void main(String[] args){

Scanner s = new Scanner(System.in);//接受客户键盘输入，在命令行中，回车结束

System.out.println( "酒店管理系统" );

Hotel h = new Hotel();

System.out.println( h );

h.print();

while (true){

System.out.println( "请输入房间编号" );

//声明变量,用于接受控制台输入数据

String no = s.next();

//预订房间

h.order(no);

h.print();

}

}

}

class Room{

//房间号

private String no;

//房间类型

private String type;

//是否被占用

private boolean isUse;

public Room(){//默认调用

super();

}

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

super();

this.no = no;

this.type = type;

this.isUse = isUse;

}

public String getNo(){

return no;

}

public void setNo(String no){

this.no = no;

}

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;

}

public String toString(){  //声明输出结果格式

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

}

}

class Hotel{

Room rooms[][];

public Hotel(){

rooms = new Room[5][4];//旅馆有五层，每层四个房间

for(int i=0; i  rooms.length; ++i){//外层for循环是循环层,内存循环是循环的每层的房间

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

if (i == 0 || i == 1) {

//后面加个空字符串,是自动数据类型转换,这样前面的数字会自动变成数字型字符串;

rooms[i][j] = new Room((i+1)*100+j+1 +"" , "标准间",false);

}

if (i == 2 || i == 3) {

rooms[i][j] = new Room((i+1)*100+j+1 +"" , "双人间",false); 

}

if (i == 4) {

rooms[i][j] = new Room((i+1)*100+j+1 +"" , "豪华间",false); 

}

}

}

}

//对外提供房间列表的打印方式

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] + " " );

}

//换行

System.out.println(  );

}

}

//提供旅馆对外预定方式

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)) {

//把对象的成员数据封装,通过成员方法访问

//1 成员变量的访问方式rooms[i][j].no;

//2 成员方法的访问方式

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

return;

}

}

}

}

}

带数据库的就算了
