    博客班级 AHPU软件工程
    作业要求 ATM自助银行服务系统
    作业目标 编码实现ATM自助银行服务系统
    学号 3180701118

    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("			1、开户
    			2、登录
    			0、退出
    ");
                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;
                }
            }
        }

                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
