【Java】银行中用户存取款业务的实现

//主要实现public class Bank {    static String bankName;//银行名称    private String name;//储户名字    private String password;//密码    private double balance;//账户余额    private double turnover;//交易额    static void welcome()    {        System.out.println("欢迎您来到"+bankName);    }    public Bank(String name,String password,double turnover)    {        this.name = name;        this.password=password;        this.turnover = turnover;        this.balance = turnover-10;        System.out.println(name+"开户成功"+"余额为："+balance);    }    //存款    public void depoist(double turnover)    {        balance = balance+turnover;        System.out.println(name+"您好，您的账户已存入"+balance+"元"+"当前余额为："+balance+"元");    }    //取款    public void withdrawl(String password,double turnover)    {        if(this.password!=password)        {            System.out.println("抱歉，你输入的密码有误");            return ;        }        if(balance-turnover>0)        {            System.out.println("您已取出"+turnover+"元"+"当前余额为"+(balance-turnover));        }        else        {            System.out.println("抱歉，你的余额已不足");        }    }    static void welcomenext()    {        System.out.println("请携带好您的随身物品，欢迎下次再来");    }}//测试public class Trade {    /**     * @param args     */    public static void main(String[] args) {        // TODO Auto-generated method stub        Bank.bankName="建设银行";        Bank.welcome();        Bank bank = new Bank("张华","123456",200.0);        bank.depoist(200.0);        bank.withdrawl("123456", 150.0);        bank.withdrawl("333456", 150.0);        bank.withdrawl("123456", 500.0);        Bank.welcomenext();    }}

代码运算结果如下：
