软件工程作业--ATM自助银行服务系统
目录
一、作业要求
编写一个ATM管理系统,语言不限,要求应包括以下主要功能:
(1)开户,销户
(2)查询账户余额
(3)存款
(4)取款
(5)转账(一个账户转到另一个账户)等...
二、代码及运行界面
test类
(Java程序的入口)
♡代码:
public class Main {
public static void main(String[] args) {
bank b=new bank ();
User u=new User();
b.menu();
}
}
User类
(主要是set、get方法和类的构造器)
♡代码:
public class User {
private String name;//姓名
private int accountId;//账号
private String password;//密码
private String address;//家庭地址
private String phone;//联系电话
private double balance;//余额
public User(){}
public User(String name, int accountId, String password, String address, String phone, double balance) {
this.name = name;
this.accountId = accountId;
this.password = password;
this.address = address;
this.phone = phone;
this.balance = balance;
}
public String getName(){
return this.name;
}
public void setName(String name){
this.name=name;
}
public int getAccountId(){
return this.accountId;
}
public void setAccountId(int accountId){
this.accountId=accountId;
}
public String getPassword(){
return this.password;
}
public void setPassword(String password){
this.password=password;
}
public String getAddress(){
return this.address;
}
public void setAddress(String address){
this.address=address;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public double getBalance(){
return this.balance;
}
public void setBalance(double balance){
this.balance=balance;
}
}
bank类
(实现ATM的操作功能)
1.菜单选项(选择开户/登录)
♡代码:
public void menu() {
Scanner sc = new Scanner(System.in);
int ch;
while(true){
System.out.println("===========欢迎使用ATM自助银行服务==========");
System.out.printf("\t\t\t1、开户\n\t\t\t2、登录\n\t\t\t0、退出\n");
System.out.println("============欢迎使用ATM自助银行服务==========");
System.out.print("输入您要操作编号:");
ch = sc.nextInt();
switch (ch) {
case 1:
setAccount();//开户
break;
case 2:
onuser = userLogin();//登录
if(onuser!=null) menu1();
break;
case 0: //退出
return;
default:
System.out.println("输入错误!请重新输入!");
break;
}
}
}
♡运行界面:
2.开户
♡代码:
//开户
public void setAccount() {
Scanner sc = new Scanner(System.in);
System.out.print("请输入姓名:");
String name = sc.next();
System.out.print("请输入家庭地址:");
String address = sc.next();
System.out.print("请输入身份证号:");
String accountId = sc.next();
System.out.print("请输入手机号:");
String phone=sc.next();
System.out.print("请输入银行卡要设置的密码:");
String pwd1 = sc.next();
System.out.print("请再次输入密码:");
String pwd2 = sc.next();
if (pwd1.equals(pwd2)) {
System.out.println(i);
user[i] = new User(name, i, pwd1, address,phone, 0);
System.out.println("开户成功!你的卡号为:" + i);
i++;
} else
System.out.println("两次密码不同!请您再一次确认密码!");
}

3.登录
♡代码:
public User userLogin() {
Scanner sc = new Scanner(System.in);
System.out.print("请输入卡号");
int aId = sc.nextInt();
System.out.print("请输入密码");
String pwd = sc.next();
for (int i = 0; i < user.length; i++) {
if (user[i] != null) {
if (aId == user[i].getAccountId() && pwd.equals(user[i].getPassword())) {
System.out.println(user[i].getName() + "先生/女士,欢迎登录!");
return user[i];
}
}
}
System.out.println("卡号或密码有误");
return null;

心得和经验
本次作业用Java实现,由于未上过Java课,都Java不熟练,所以用简单的类编写,未用GUI实现图形化。
