软件工程作业--ATM自助银行服务系统

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;
            }
        }
    }

            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!");
    }

            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];
                    }
                }

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。
