Java项目实现模拟ATM机
本文实例为大家分享了java实现模拟ATM机的具体代码,供大家参考,具体内容如下
项目名称
模拟ATM机
项目描述
简单实现ATM机功能
代码实现
测试类
public class Test {
//模拟多功能ATM机
public static void main(String[] args) {
ATM atm = new ATM();
atm.opearte();
}
}
主类:实现主方法
public class ATM {
private Bank bank;
public ATM(){
bank = new Bank();
}
private void success(BankCard bankCard) {
while (true) {
System.out.println("请选择:1、查询余额,2、取款,3、存款,4、转账,5、退卡");
Scanner scanner = new Scanner(System.in);
int choice = scanner.nextInt();
if (choice == 5) {
return;
}
switch (choice) {
case 1:
int money = bank.printf(bankCard);
System.out.println("余额:" + money);
break;
case 2:
System.out.println("请输入取款金额:");
money = scanner.nextInt();
bankCard.withdraw(money);
break;
case 3:
System.out.println("请输入存款金额:");
money = scanner.nextInt();
bankCard.deposit(money);
break;
case 4:
System.out.println("请输入对方账户id:");
int id = scanner.nextInt();
BankCard card = bank.transfer(id);
mRxNx if(card != null){
System.out.println("请输入转账金额:");
money = scanner.nextInt();
if(money <= bankCard.getMoney()){
bankCard.withdraw(money);
card.deposit(money);
}else {
System.out.println("转账失败");
}
}else {
System.out.println("未找到该账户");
}
break;
default:
}
}
}
private void login(){ //登录
System.out.println("请输入账号,密码");
Scanner scanner = new Scanner(System.in);
int id = scanner.nextInt();
int password = scanner.nextInt();
BankCard bankCard = bank.search(id,password);
if(bankCard != null){
System.out.println("登录成功");
success(bankCard);
}else {
System.out.println("登录失败,请注册");
}
}
private void register(){ //注册
System.out.println("请输入账号,密码");
Scanner scanner = new Scanner(System.in);
int id = scanner.nextInt();
int password = scanner.nextInt();
BankCard bankCard = bank.search(id,password);
if(bankCard != null){
System.out.println("该账号已存在,请直接登录");
}else {
bank.addcard(id,password);
System.out.println("注册成功");
}
}
public void opearte() {
while (true) {
System.out.println("请选择:1、登录,2、注册,3、退出");
Scanner scanner = new Scanner(System.in);
int choice = scanner.nextInt();
if (choice == 3) {
return;
}

银行卡类:不同账户的操作
public class BankCard {
