【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()

4000
{
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);
