java编写的模拟ATM取款机程序

我现写的： import java.util.Scannerpublic class ATM {

private static String theName = "admin"

private static String thePassword = "123456"

private static int balance = 10000

public static void getBalance(){

System.out.println("当前余额：" + balance)

}

public static void drawMoney(Scanner sc){

int money = 0

System.out.println("请输入取款金额：")

money = sc.nextInt()

String type = ""

if (balance >0) {

if (balance >= money) {

if (money <= 5000) {

balance = balance - money

type = "请在30秒内提取现金...\n剩余余额："+balance

} else if (money <= 0) {

type = "金额错误"

} else {

type = "超出最大限制金额"

}

} else {

type = "超出最大余额"

}

} else {

type = "余额不足"

}

System.out.println(type)

}

public static void bankMoney(Scanner sc){

int money = 0

System.out.println("请输入存储金额：")

money = sc.nextInt()

String type = ""

if (money >0) {

balance = balance + money

type = "存储成功，现有余额：" + balance

} else {

type = "存储金额不能为负"

}

System.out.println(type)

}

public static void updatePass(Scanner sc){

String oldPass = ""

String newPass1 = ""

String newPass2 = ""

while(true){

System.out.println("请输入原密码：")

oldPass = sc.next()

if (oldPass.equals(thePassword)) {

break

} else {

System.out.println("密码错误，请重新输入")

}

}

while(true){

System.out.println("请输入新密码")

newPass1 = sc.next()

System.out.println("再次输入")

newPass2 = sc.next()

if (newPass1.equals(newPass2)) {

if (!isSame(newPass1)) {

thePassword = newPass1

System.out.println("修改成功")

break

} else {

System.out.println("所有字符不能相同，重新输入")

}

} else {

System.out.println("两次输入不一致，重新输入")

}

}

}

public static boolean isSame(String string){

boolean bool = false

for (int i = 0i <string.length() - 1i++) {

char char1 = string.charAt(i)

for (int j = i + 1j <string.length()j++) {

char char2 = string.charAt(j)

if (char1 == char2) {

}

}

}

}

System.out.println("请输入密码：")

password = sc.next()

if (name.equals(theName) &&password.equals(thePassword)) {

break

} else {

System.out.println("账号或密码错误，请重新输入!")

}

}

while(true){

int operate = 0

System.out.println("请选择你要进行的 *** 作：\n1、查询 2、取款 3、存款 4、修改密码 0、退出")

operate = sc.nextInt()

if (0 == operate) {

System.out.println("谢谢使用！")

break

原程序的错误有：

1.a为int型。去掉‘’

2.ATM1 atm = new ATM1 ， 类名要和前面的一致

3.加入int a = sc.nextInt()// 请加入此句 进而选择相应功能，

PS：程序已调好，试试吧。

import java.util.Scanner

public class ATM1 {

Scanner sc = new Scanner(System.in)

private String name = "lorin"

private double password = 123

private double money = 500

public void aloha(){

System.out.println("***********************")

System.out.println("* *")

System.out.println("* 欢迎使用ATM *")

System.out.println("* *")

System.out.println("* 制作人：lorin *")

System.out.println("* *")

System.out.println("* *")
