java取款機
⑴ java編寫的模擬ATM取款機程序
我現寫的： import java.util.Scanner;public class ATM {
private static String theName = "admin";
private static String thePassword = "123456";
private static int balance = 10000;
public static void getBalance(){
System.out.println("當前余額：" + balance);
}
public static void drawMoney(Scanner sc){
int money = 0;
System.out.println("請輸入取款金額：");
money = sc.nextInt();
String type = "";
if (balance > 0) {
if (balance >= money) {
if (money <= 5000) {
balance = balance - money;
type = "請在30秒內提取現金...\n剩餘余額："+balance;
} else if (money <= 0) {
type = "金額錯誤";
} else {
type = "超出最大限制金額";
}
} else {
type = "超出最大余額";
}
} else {
type = "余額不足";
}
System.out.println(type);
}
public static void bankMoney(Scanner sc){
int money = 0;
System.out.println("請輸入存儲金額：");
money = sc.nextInt();
String type = "";
if (money > 0) {
balance = balance + money;
type = "存儲成功，現有餘額：" + balance;
} else {
type = "存儲金額不能為負";
}
System.out.println(type);
}
public static void updatePass(Scanner sc){
String oldPass = "";
String newPass1 = "";
String newPass2 = "";
while(true){
System.out.println("請輸入原密碼：");
oldPass = sc.next();
if (oldPass.equals(thePassword)) {
break;
} else {
System.out.println("密碼錯誤，請重新輸入");
}
}
while(true){
System.out.println("請輸入新密碼");
newPass1 = sc.next();
System.out.println("再次輸入");
newPass2 = sc.next();
if (newPass1.equals(newPass2)) {
if (!isSame(newPass1)) {
thePassword = newPass1;
System.out.println("修改成功");
break;
} else {
System.out.println("所有字元不能相同，重新輸入");
}
} else {
System.out.println("兩次輸入不一致，重新輸入");
}
}
}
public static boolean isSame(String string){
boolean bool = false;
for (int i = 0; i < string.length() - 1; i++) {
char char1 = string.charAt(i);
for (int j = i + 1; j < string.length(); j++) {
char char2 = string.charAt(j);
if (char1 == char2) {
bool = true;
break;
}
}
}
return bool;
}
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while(true){
String name = "";
String password = "";
System.out.println("請輸入賬號：");
name = sc.next();
System.out.println("請輸入密碼：");
password = sc.next();
if (name.equals(theName) && password.equals(thePassword)) {
break;
} else {
System.out.println("賬號或密碼錯誤，請重新輸入!");
}
}
while(true){
int operate = 0;
System.out.println("請選擇你要進行的操作：\n1、查詢 2、取款 3、存款 4、修改密碼 0、退出");
operate = sc.nextInt();
if (0 == operate) {
System.out.println("謝謝使用！");
break;
} else if (1 == operate) {
getBalance();
} else if (2 == operate) {
drawMoney(sc);
} else if (3 == operate) {
bankMoney(sc);
} else if (4 == operate) {
updatePass(sc);
}
}
}
}
⑵ 求高手用JAVA編寫一個模擬ATM機取款業務需求如下：
樓主您好，編碼如下，直接運行即可：
import java.util.Scanner;
public class AtmGetMoney {
public static void main(String[] args) {
String password = "111111";
int count = 0;
int a = 0;
while(count<3){
System.out.println("請輸入銀行卡密碼： ");
Scanner scan = new Scanner(System.in);
String passwd = scan.nextLine();
while(passwd.equals(password)){
System.out.println("請輸入取款金額： ");
int amount = scan.nextInt();
if(amount%100 == 0 && amount <= 1000){
System.out.println("您的取款金額為： "+amount);
System.out.println("交易完成，請讀卡！");
a = a + 1;
break;
}
else {
System.out.println("只能提取100元紙幣，要求最低0，最高1000！");
continue;
}
}
if (a == 1){
break;
}
else if (count < 2) {
System.out.println("銀行卡密碼錯誤");
count = count + 1;
continue;
}
else {
System.out.println("密碼錯誤請讀卡");
break;
}
}
}
}
⑶ 使用Java語言中（類和對象）編寫： ATM自動存取款機的程序
很簡單的例子，我把代碼貼出來吧
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)中國農業銀行ATM自動存取款機☆☆☆☆☆☆☆☆☆☆☆☆☆");
System.out.println("\n\t\t\t\t1.存款業務");
System.out.println("\n\t\t\t\t2.取款業務");
System.out.println("\n\t\t\t\t3.查詢余額");
System.out.println("\n\t\t\t\t4.退出ATM系統");
System.out.println("\n☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆中國農業銀行歡迎您的使用☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆");
in = new Scanner(System.in);
switch (in.nextInt()) {
case 1:
System.out.println("請輸入您的存款數額！");
depositMoney = in.nextDouble();
if(depositMoney < 0)
System.out.println("您的輸入無效，請重新輸入!");
result = account.deposit(depositMoney);
if(result == 0){
System.out.println("存款業務完成，是否顯示余額？Y/N");
if("Y".equalsIgnoreCase(in.next())){
System.out.println("您當前的余額為："+account.checkCurrent());
}else {
break;
}
}else {
System.out.println("無法完成交易！");
break;
}
break;
case 2:
System.out.println("請輸入您的取款數額！");
drawMoney = in.nextDouble();
if (drawMoney < 0) {
System.out.println("您的輸入無效，請重新輸入!");
}
result = account.withDraw(drawMoney);
if (result == 0) {
System.out.println("存款業務完成，是否顯示余額？Y/N");
if("Y".equalsIgnoreCase(in.next())){
System.out.println("您當前的余額為："+account.checkCurrent());
}else {
break;
}
} else {
System.out.println("無法完成交易！");
break;
}
case 3:
System.out.println("您當前的余額為："+account.checkCurrent());
break;
case 4:
break;
default:
break;
}
}
}
}
public class Account {
private double currentMoney;//當前余額
public double getCurrentMoney() {
return currentMoney;
}
public void setCurrentMoney(double currentMoney) {
if (currentMoney > 0) {
this.currentMoney = currentMoney;
}
}
/**
* 取款業務
* @param drawMoney
* @return 0代表成功，1代表失敗
*/
public int withDraw(double drawMoney) {
if (currentMoney > 0 && drawMoney <= currentMoney) {
currentMoney -= drawMoney;
} else {
System.out.println("您的余額已不足！");
return 1;
}
return 0;
}
/**
* 存款業務
* @param depositMoney
* @return 0代表成功，1代表失敗
*/
public int deposit(double depositMoney) {
if (depositMoney > 0) {
currentMoney += depositMoney;
return 0;
}else {
System.out.println("您提交的存款為負數，無法完成存款交易");
return -1;
}
}
/**
* 查詢余額業務
* @return
*/
public double checkCurrent() {
return currentMoney;
}
}
⑷ 利用JAVA語言二重循環實現ATM機取款過程！
public static void main(String[] args) {
Scanner s, money;
int pass = 1111;
int tempass;
int choose = 0;
mkar: for (int i = 0; i < 3; i++) {
s = new Scanner(System.in);
money = new Scanner(System.in);
tempass = s.nextInt();
if (tempass == pass) {
for (;;) {
System.out.println("請輸入1到9的數字選擇你要取款的");
choose = money.nextInt();
switch (choose) {
case 1:
System.out.println("取款100");
break;
case 2:
System.out.println("取款200");
break;
case 3:
System.out.println("取款300");
break;
case 4:
System.out.println("取款400");
break;
case 5:
System.out.println("取款500");
break;
case 6:
System.out.println("取款600");
break;
case 7:
System.out.println("取款700");
break;
case 8:
System.out.println("取款800");
break;
case 9:
System.out.println("取款900");
break;
case 0:System.out.println("操作成功退出");
break mkar;
}
}
} else {
System.out.println("密碼錯誤");
}
}
}
看下是不是你的要求，也可以自己改下
⑸ Java編程實現程序用於模擬ATM取款機。
package demo;
import java.util.Scanner;
public class Test3 {
public static void main(String[] args) {
Scanner scanner =new Scanner(System.in);
int cnt=3;
String username = null;
String password = null;
double money = 1000;
String targetName = "admin33";
double targetMoney = 1000;
while(true){
if(username!=null&&password!=null){
if("admin".equals(username) && "123".equals(password)){
System.out.println("歡迎光臨");
while(true){
System.out.println("請選擇您的操作 1 取錢 2 存錢 3 轉賬 4 查詢 5 退出 ");
int n = scanner.nextInt();
if(n==1){//取錢
System.out.println("請輸入金額");
int getter = scanner.nextInt();
if(getter>=0){
if(getter<=5000){
if(getter<=money){
money-=getter;
}else{
System.out.println("余額不足");
}
}else{
System.out.println("單筆只能取5000及以下");
}
}else{
System.out.println("銀行不到給");
}
}else if(n==2){//存錢
System.out.println("請輸入金額");
int save = scanner.nextInt();
if(save>=0){
money+=save;
}
}else if(n==3){//轉賬
System.out.println("請輸入目標賬戶");
String target = scanner.next();
if(target.equals(targetName)){
System.out.println("請輸入金額");
int getter = scanner.nextInt();
if(getter>=0){
if(getter<=5000){
if(getter<=money){

targetMoney+=getter;
}else{
System.out.println("余額不足");
}
}else{
System.out.println("單筆只能取5000及以下");
}
}else{
System.out.println("銀行不到給");
}
}
}else if(n==4){//查詢
System.out.println(money);
}else if(n==5){//退出
System.exit(0);
}else{
System.out.println("沒有該項服務");
}
}
}else{
cnt--;
System.out.println("輸入錯誤，您還有"+cnt+"次機會");
username=null;
password=null;
if(cnt<=0){
System.out.println("對不起，您的賬號被凍結，請到最近的營業廳解除凍結");
System.exit(0);
}
}
}else{
System.out.println("請輸入您的賬號");
username = scanner.next();
System.out.println("請輸入您的密碼");
password = scanner.next();
}
}
}
}

}
//存款的方法
publicvoidsave(doublecount){
money+=count;
}
//取款的方法
publicvoiddraw(doublecount){
money-=count;
}
publicdoublegetMoney(){
