⑴ 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;
}
}
⑵ 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){
money-=getter;
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();
}
}
}
}
⑶ ATM取款機系統用JAVA怎麼做/
這里有個模擬
用戶：blucastle ，密碼： 123
import java.util.Scanner;
public class ATM1 {
Scanner sc = new Scanner(System.in);
private String name = "blucastle";
private double password = 123;
private double money = 500;
public void aloha(){
System.out.println("***********************");
System.out.println("* *");
System.out.println("* 歡迎使用ATM *");
System.out.println("* *");
System.out.println("* 製作人：blucastle*");
System.out.println("* *");
System.out.println("* *");
System.out.println("************************");
System.out.println("請輸入用戶名：");
String s = sc.next();
if(s.equals("blucastle")) {
System.out.println("請輸入密碼：");
int ss = sc.nextInt();
if(ss == 123) {
land();
}else{
System.out.println("密碼錯誤，系統退出");
System.exit(0);
}
}else{
System.out.println("用戶名錯誤，系統退出");
System.exit(0);
}
}
//登陸頁面
public void land(){
System.out.println("請選擇操作界面：1取款，2存款，3查詢，4轉賬，5退出");
int a = sc.nextInt();// 請加入此句
switch(a){
case 1 : // 去掉『』 因為a 為int型。
get();
break;
case 2 :
set();
break;
case 3 :
query();
break;
case 4 :
divert();
break;
case 5 :
SetOut();
break;
}
}
//取款
public void get(){
System.out.println("請輸入取款金額：");
int a = sc.nextInt();
if(a>money){
System.out.println("余額不足！");
}else{
money-=a;
System.out.println("當前余額為："+money);
land();
}
}
//存款
public void set(){
System.out.println("請輸入存款金額：");
int a = sc.nextInt();
money+=a;
System.out.println("當前余額為："+money);
land();
}
//查詢
public void query(){
System.out.println("當前余額為："+money);
land();
}
//轉賬
public void divert(){
System.out.println("該功能站未開放！");
land();
}
//退出
public void SetOut(){
System.exit(0);
}
public static void main(String[] args) {
ATM1 atm = new ATM1();
atm.aloha();
}
}
⑷ 用java編寫的ATM機源代碼
/** * @author admin * 該程序的功能為實現模擬銀行ATM自動取款機提款,查詢等功能. */ import Java.io.*; /*該類為實現客戶信息及部分功能*/ class Account { private String code =null; //信用卡號 private String name =null; //客戶姓名 private String password=null; //客戶密碼 private double money =0.0; //卡里金額 public Account(String code,String name,String password,double money) { this.code=code; this.name=name; this.password=password; this.money=money; } protected String get_Code() { return code; } protected String get_Name() { return name; } protected String get_Password() { return password; } public double get_Money() { return money; } /*得到剩餘的錢的數目*/ protected void set_Balance(double mon) { money -= mon; } } /**********實現具體取款機功能*********/ class ATM { Account act; // private String name; // private String pwd; public ATM() { act=new Account("000000","Devil","123456",50000); } /***********歡迎界面***********/ protected void Welcome() { String str="---------------------------------"; System.out.print(str "\n" "歡迎使用Angel模擬自動取款機程序.\n" str "\n"); System.out.print(" 1.>取款." "\n" " 2.>查詢信息." "\n" " 3.>密碼設置." "\n" " 4.>退出系統." "\n"); } /**********登陸系統**********/ protected void Load_Sys() throws Exception { String card,pwd; int counter=0; BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); do { System.out.println("請輸入您的信用卡號:"); card=br.readLine(); System.out.println("請輸入您的密碼:"); pwd=br.readLine(); if(!isRight(card,pwd)) { System.out.println("您的卡號或密碼輸入有誤."); counter ; } else SysOpter(); }while(counter<3); Lock_Sys(); } 回復獲取全部
⑸ 自動取款機上面的程序是java程序嗎
不是，是c語言寫的，java也可以，但是不採用java，效率沒有c語言高。
⑹ 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;
}
}
}
}
