用JAVA制作简单的ATM的代码 求教
ok，稍等
呵呵，已经给你拆分成了两个独立的类了。
我再吧注释加起吧。
哪儿不清楚的可以给我留言嘛，刚开始学习的时候就要多看看别人写的代码，然后从中学习。这里写的用到了简单的封装面向对象静态类，你可以在多了解下，不难的。
import java.util.Scanner;
public class Atm {
//显示菜单
static void showMenu() {
System.out.println();
System.out.print("1.查询账户余额\n");
System.out.print("2.存款\n");
System.out.print("3.取款\n");
System.out.print("0.退出\n");
System.out.print("请选择操作:");
}
public static void main(String[] arg) {
//创建一个account的对象
Account account = new Account();
System.out.println("*******欢迎使用**********");
//循环操作提示
while (true) {
showMenu();//调用显示菜单的方法
//得到用户的输入
Scanner scanner = new Scanner(System.in);
int input = scanner.nextInt();
switch (input) {
case 1:
account.query();
break;
case 2:
System.out.print("请输入存款额：");
float in = scanner.nextFloat();
account.in(in);
account.query();
break;
case 3:
System.out.print("请输入取款额：");
float out = scanner.nextFloat();
account.out(out);
account.query();
break;
case 0:
System.out.println("谢谢使用");
System.exit(0); //终止程序
break;
default:
System.out.println("输入有误");
}
}
}
}
//帐号类
class Account {
private float money = 8000;
// 查询账户余额
public void query() {
System.out.println("账户余额：" + money);
}
// 取出，out是取出的存款数
public void out(float out) {
if (money out) {
System.out.println("账户余额不足");
}
this.money -= money;
}
// 存入，in是输入的存款数
public void in(float in) {
this.money += in;
}
}
