很简单的例子，我把代码贴出来吧

import javautilScanner;

public class ATM {

/

@param args

/

public static void main(String[] args) {

Scanner in = null;

int result;

double drawMoney;

double depositMoney;

Account account = new Account();

while (true) {

Systemoutprintln("☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆(ABC)中国农业银行ATM自动存取款机☆☆☆☆☆☆☆☆☆☆☆☆☆");

Systemoutprintln("\n\t\t\t\t3查询余额");

Systemoutprintln("\n\t\t\t\t4退出ATM系统");

Systemoutprintln("\n☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆中国农业银行欢迎您的使用☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆");

in = new Scanner(Systemin);

switch (innextInt()) {

case 1:

Systemoutprintln("请输入您的存款数额！");

depositMoney = innextDouble();

if(depositMoney < 0)

Systemoutprintln("您的输入无效，请重新输入!");

result = accountdeposit(depositMoney);

if(result == 0){

Systemoutprintln("存款业务完成，是否显示余额？Y/N");

if("Y"equalsIgnoreCase(innext())){

Systemoutprintln("您当前的余额为："+accountcheckCurrent());

}else {

break;

}

}else {

break;

}

break;

case 2:

case 3:

break;

case 4:

break;

}

}

}

}

public class Account {

private double currentMoney;//当前余额

public double getCurrentMoney() {

}

public void setCurrentMoney(double currentMoney) {

}

}

/

取款业务

@param drawMoney

@return 0代表成功，1代表失败

/

存款业务
