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 {
/**

*/
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);

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;
}
}
/**

*/

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) {

return 0;
}else {

return -1;
}

// 取款的方法
