System.out.println("欢迎光临");

while(true){

使用Java语言中（类和对象）编写： ATM自动存取款机的程序？

很简单的例子，我把代码贴出来吧

import java.util.Scanner;

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) {

System.out.println("☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆(ABC)中国农业银行ATM自动存取款机☆☆☆☆☆☆☆☆☆☆☆☆☆");

System.out.println("\n\t\t\t\t1.存款业务");

System.out.println("\n\t\t\t\t2.取款业务");

System.out.println("\n\t\t\t\t3.查询余额");

System.out.println("\n\t\t\t\t4.退出ATM系统");

System.out.println("\n☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆中国农业银行欢迎您的使用☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆");

in = new Scanner(System.in);

switch (in.nextInt()) {

case 1:

System.out.println("请输入您的存款数额！");

depositMoney = in.nextDouble();

if(depositMoney 0)

System.out.println("您的输入无效，请重新输入!");

result = account.deposit(depositMoney);

if(result == 0){

System.out.println("存款业务完成，是否显示余额？Y/N");

if("Y".equalsIgnoreCase(in.next())){

System.out.println("您当前的余额为："+account.checkCurrent());

}else {

break;

}

}else {

System.out.println("无法完成交易！");

break;

}

break;

case 2:

System.out.println("请输入您的取款数额！");

drawMoney = in.nextDouble();

if (drawMoney 0) {

System.out.println("您的输入无效，请重新输入!");

}

result = account.withDraw(drawMoney);

if (result == 0) {

System.out.println("存款业务完成，是否显示余额？Y/N");

if("Y".equalsIgnoreCase(in.next())){

System.out.println("您当前的余额为："+account.checkCurrent());

}else {

break;

}

} else {

System.out.println("无法完成交易！");

break;

}

case 3:

System.out.println("您当前的余额为："+account.checkCurrent());

break;

case 4:

break;

default:

break;

}

}

}

}

public class Account {

private double currentMoney;//当前余额

public double getCurrentMoney() {

return currentMoney;

}

public void setCurrentMoney(double currentMoney) {

if (currentMoney 0) {

this.currentMoney = currentMoney;

}

}

/**

* @param drawMoney

* @return 0代表成功，1代表失败

*/

public int withDraw(double drawMoney) {

if (currentMoney 0 drawMoney = currentMoney) {

currentMoney -= drawMoney;

} else {

System.out.println("您的余额已不足！");

return 1;

}

return 0;

}

/**

* 存款业务

* @param depositMoney

* @return 0代表成功，1代表失败

*/

public int deposit(double depositMoney) {

if (depositMoney 0) {

currentMoney += depositMoney;

return 0;

}else {

System.out.println("您提交的存款为负数，无法完成存款交易");

return -1;

}

}

/**

* 查询余额业务

* @return

*/

public double checkCurrent() {

return currentMoney;

}

}
