作业题目:

模拟银行账户业务:编写Account类,添加带参方法实现存款和取款业务,开户时帐户初始金额为0元,取款时如果余额不足给出提示。

我好像把简单的问题复杂化了... :@(喜极而泣)

我的运行截图:

:@(喷水) 不知道要不要加啥卡号和密码,就直接加上了。

(借鉴没啥问题,别直接复制,不然查重就不好了) ::(狂汗)

代码如下:

Account类:

public class Account {
    private String cardnumber;
    private String password;
    private double balance;
    public double getBalance() {
        return balance;
    }
    public String getCardnumber() {
        return cardnumber;
    }
    public String getPassword() {
        return password;
    }
    // 构造Account方法
    public Account(String cardnumber, String password, double balance) {
        this.cardnumber = cardnumber;
        this.password = password;
        this.balance = balance;
    }
    // 取款加款
    public void ChangeBalance(double money) {
        if (money >= 0) {
            this.balance = balance + money;
            System.out.println("存入成功!您的余额为:" + this.balance + "元");
        } else if (money < 0 && this.balance + money >= 0) {
            this.balance = balance + money;
            System.out.println("取出成功!您的余额为:" + this.balance + "元");
        } else {
            System.out.println("账户余额不足!取款失败");
        }
    }
}

test类:

import java.util.Scanner;
public class test {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        // 创建user1对象,使用构造方法,卡号:100000000,密码:abc123,余额0
        Account user1 = new Account("100000000", "abc123", 0);
        Scanner in = new Scanner(System.in);
        System.out.print("请输入您的卡号:");
        if (in.next().equals(user1.getCardnumber())) {
            System.out.print("请输入您的密码:");
            if (user1.getPassword().equals(in.next())) {
                System.out.print("验证成功!\n您的账户余额为:" + user1.getBalance() + "元\n");
                for (int i = 0;;i++) {
                    // for循环进行服务直到用户结束跳出
                    // switch进行判断
                    System.out.println("请输入您要办理的业务(存款/取款/结束)");
                    switch (in.next()) {
                    case "存款":
                        System.out.print("请输入您的存款金额:");
                        Double addmoney = in.nextDouble();
                        if (addmoney > 0) {
                            user1.ChangeBalance(addmoney);
                        } else {
                            System.out.println("您输入的金额不合法");
                        }
                        break;
                    case "取款":
                        System.out.print("请输入您的取款金额:");
                        Double deletemoney = in.nextDouble();
                        if (deletemoney > 0) {
                            user1.ChangeBalance(-deletemoney);
                        } else{
                            System.out.println("您输入的金额不合法");
                        }
                        break;
                    case "结束":
                        System.out.println("欢迎再次光临~");
                        return;
                    }
                }
            } else
                System.out.println("密码错误!");
        } else {
            System.out.println("卡号不存在!");
        }
        in.close();
    }
}

:@(咽气) 没咯.写过的留自己个足迹 ::(吐舌)
