Java接口公交卡（金陵一卡通）问题

这次老师没有发题目，内容大致如下：（加上了个人的修改）

 

二话不说上代码。这次算上两个接口和一个主类，总共有11个文件。

1.Card.java源文件：

package BusCard;

 

public class Card {

Card(){

System.out.println("A Card has been produced!");

}

public void Using(){

System.out.println("Card is using!");

}

}

**************************************************************************

2.Buscard,java源文件:

package BusCard;

 

public class Buscard extends Card{

Buscard(){

System.out.println("A Buscard has been produced!");

}

public void Using(){

System.out.println("Buscard is using!");

}

}

*****************************************************************************

3.park.java源文件：

package BusCard;

 

public class park {

String name;

}

********************************************************************************

4.hospital.java源文件：

package BusCard;

 

public class hospital {

String name;

}

******************************************************************************

5.SeeDoctorable.java源文件：（注意这里创建文件时选interface而不是class，虽然没啥影响……）

package BusCard;

 

interface SeeDoctorable {

public void SeeDoctor(hospital p); //使用医疗卡

public void showh(); //显示能使用医疗卡的医院

}

**********************************************************************************

6.Parkable.java源文件：(注意点同上……)

package BusCard;

 

public interface Parkable {

public void Park(park pa); //公园卡功能

public void showp(); //显示能使用公园卡的公园名字

}

***********************************************************************************

7.NoneBusCard.java源文件：

package BusCard;

 

public class NoneBusCard {

NoneBusCard(){

System.out.println("A NoneBusCard has been produced!");

}

public void Using(){

System.out.println("NoneBusCard is using!");

}

}

******************************************************************************

8.RealBusCard.java源文件：

package BusCard;

import java.util.*;

public class RealBusCard implements //连接接口

SeeDoctorable,Parkable{

int Cardnumber;

String username;

Account user;

RealBusCard(){ //创建实名卡

Account u = new Account();

this.Cardnumber = u.Accountnumber;

this.user = u;

System.out.println("Please input your name:");

Scanner cin = new Scanner(System.in);

this.username = cin.next();

user.username = this.username;

System.out.println("A RealBusCard has been produced!");

System.out.println("Your cardnumber is "+this.Cardnumber);

}

public void Using(){

System.out.println("RealBusCard is using!");

}

public void RealBusCard_set(){}

public void SeeDoctor(hospital p){ //接口1,医疗卡功能

if (RegisterPool.if_inhospital(p)==true) {

System.out.println("RealBusCard is hospitalable!");

}

else {

System.out.println("RealBusCard is not hospitalable!\n"

+ "Because the hospital is not in the list!");

}

}

public void Park(park pa){ //接口2，公园卡功能

if (RegisterPool.if_inpark(pa)==true) {

System.out.println("RealBusCard is parkable!");

}

else {

System.out.println("RealBusCard is not parkable!\n"

+ "Because the park is not in the list!");

}

}

public void showp() { //显示能使用公园卡的公园名字

System.out.println("You can visit the following park:");

for (int i=0;i<RegisterPool.pi;i++) {

System.out.println(RegisterPool.p[i].name);

}

}

public void showh() { //显示能使用医疗卡的医院

System.out.println("You can visit the following hospital :");

for (int i=0;i<RegisterPool.hi;i++) {

System.out.println(RegisterPool.h[i].name);

}

}

}

****************************************************************************

9.RegisterPool源文件：

package BusCard;

 

public class RegisterPool {

static hospital[] h = new hospital[10];

static park[] p = new park[10];

static int hi = 0; //医院序号

static int pi = 0; //公园序号

 

static void newhospital(hospital ho){ //添加医院信息

h[hi] = ho;

hi++;

System.out.println(ho.name+"has been created!");

}

static void newpark(park pa){ //添加公园信息

p[pi] = pa;

pi++;

System.out.println(pa.name+"has been created!");

}

static void deletehospital(hospital ho){ //删除医院信息

for (int i=0;i<10;i++) {

if (ho==RegisterPool.h[i]) {

RegisterPool.h[i] = null;

RegisterPool.hi--;

break;

}

}

System.out.println(ho.name+"has been deleted!");

}

static void deletepark(park pa){//删除公园信息

for (int i=0;i<10;i++) {

if (pa==RegisterPool.p[i]) {

RegisterPool.p[i] = null;

RegisterPool.pi--;

break;

}

}

System.out.println(pa.name+"has been deleted!");

}

static boolean if_inhospital(hospital ho){ //检测医院是否在列表中

boolean flag = false;

for (int i =0;i<10;i++) {

if (ho==RegisterPool.h[i]) {

flag = true;

break;

}

}

return flag;

}

static boolean if_inpark(park pa){ //检测公园是否在列表中

boolean flag = false;

for (int i =0;i<10;i++) {

if (pa==RegisterPool.p[i]) {

flag = true;

break;

}

}

return flag;

}

}

10.Account.java源文件：

package BusCard;

 

public class Account {

static int Accountnumber = 1001;

String username;

Account(){

Accountnumber++;

//每次创造一张实名卡就使卡号+1

}

}

*************************************************************************************

11.Cardmain.java源文件：

package BusCard;

 

public class Cardmain {

 

public static void main(String[] args) {

// TODO Auto-generated method stub

hospital A = new hospital(); //创建基础医院和公园信息。

A.name = "中山医院";

hospital A2 = new hospital(); //创建基础医院和公园信息。

A2.name = "武警医院";

hospital A3 = new hospital(); //创建基础医院和公园信息。

A3.name = "卫岗社区医院";

park B = new park();

B.name = "下马坊公园";

park B2 = new park();

B2.name = "仙林湖公园";

RegisterPool.newhospital(A);

RegisterPool.newhospital(A2);

RegisterPool.newhospital(A3);

RegisterPool.newpark(B);

RealBusCard C1 = new RealBusCard(); //创建实名卡

C1.showh();

C1.showp();

C1.Using(); //使用

C1.SeeDoctor(A); //医疗卡功能，正常使用

C1.Park(B); //公园卡功能,正常使用

C1.Park(B2); //公园卡功能,非法使用，公园列表中没有B2

}

 

}
