一、问题描述
烛九幽穿越到了九州修仙界，加入了人族第一大势力：仙盟，他发现宗门的任务系统有点眼熟，就是披着仙侠皮的ATM系统。下面我们就来实现仙侠版的ATM系统。
二、基本流程
定义property类
注册账户
账户登录
三、具体步骤
1.定义属性类
/**
* 定义属性类
*/
class property{
private String name;//姓名
private String ID;//身份号
private String password;//密码
private int age;//年龄
private String race;//种族
private String quality;//修为
private int contribution;//贡献点
public property(String name, String ID, String password, int age, String race, String quality, int contribution) {
this.name = name;
this.ID = ID;
this.password = password;
this.age = age;
this.race = race;
this.quality = quality;
this.contribution = contribution;
}
public property() {
}
public String getQuality() {
return quality;
}
public void setQuality(String quality) {
this.quality = quality;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getID() {
return ID;
}
public void setID(String ID) {
this.ID = ID;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getRace() {
return race;
}
public void setRace(String race) {
this.race = race;
}
public int getContribution() {
return contribution;
}
public void setContribution(int contribution) {
this.contribution = contribution;
}
}
2.菜单栏
private static void menu() {
System.out.println("-----------------欢迎道友来到仙盟---------------------");
System.out.println("请您选择操作：");
System.out.println("1.注册账户");
System.out.println("2.登录系统");
System.out.println("3.退出");
}
3.账户注册
(1)根据ID获取账户
/**
* 通过ID获得账户信息
*
* @param proArrayList 集合
* @param ID
* @return 找到的账户信息（如果未找到，返回null）
*/
private static property getproByID(ArrayList<property> proArrayList, String ID) {
for (int i = 0; i < proArrayList.size(); i++) {
if(ID.equals(proArrayList.get(i).getID()))
return proArrayList.get(i);
}
return null;
}
(2)获取注册ID
/**
* 获取不重复的ID
* @return ID
*/
private static String getPropertyID(ArrayList<property> proArrayList) {
Random ran = new Random();
while(true){
StringBuilder sb=new StringBuilder();
for (int i = 0; i < 9; i++) {
sb.append(ran.nextInt(10));
}
String ID = sb.toString();
property pro = getproByID(proArrayList,ID);
if(pro==null)
return ID;
}
}
(3)注册账户
/**
* 进入注册/登录界面
* @param sca 扫描器
* @param proArrayList 集合
*/
private static void register(Scanner sca, ArrayList<property> proArrayList) {
System.out.println("-----------------注册---------------------");
property pro = new property();
System.out.println("请您输入您的姓名：");
String name = sca.next();
pro.setName(name);
System.out.println("请输入您的年龄：");
int age = sca.nextInt();
pro.setAge(age);
System.out.println("请您输入您的种族：");
String race = sca.next();
pro.setRace(race);
System.out.println("请您输入您的修为：");
String quality = sca.next();
pro.setQuality(quality);
String ID;
ID = getPropertyID(proArrayList);
pro.setID(ID);
System.out.println("请您输入登录密码：");
String password = sca.next();
pro.setPassword(password);
System.out.println("尊敬的【"+name+"】道友，您的登录ID是："+ID);
proArrayList.add(pro);//添加到集合中
}
4.账户登录
/**
* 登录系统
* @param sca 扫描器
* @param proArrayList 集合
*/
private static void longin(Scanner sca, ArrayList<property> proArrayList) {
while (true){
System.out.println("请您输入您的登录ID：");
String ID = sca.next();
property pro = getproByID(proArrayList,ID);
if(pro == null)
{
System.out.println("系统中未查询到该用户，请您检查ID输入是否正确，请重新输入！");
}
else{
while (true){
System.out.println("请您输入登录密码：");
String password = sca.next();
if(pro.getPassword().equals(password)){
System.out.println("密码输入正确！");
System.out.println("登录成功！");
users_function(sca,pro,proArrayList);
break;//登录成功，退出内循环
}
else {

break;
case 2:
//交易
deal_property(sca,pro,proArrayList);
break;
case 3:
//退出
flag = quit_porperty();
break;
case 4:

五、效果展示
1.账户注册
2.账户登录
(1)查询属性
(2)交易界面
(1)存款
(2)取款
(3)转账
(4)退出交易系统
(3)退出登录
(4)注销账户
此时我们再登录韩立的账户，发现已经不能登录了！
(5)登录【萧炎】的账户
刚才转账的1000贡献点已到账!
