㈠ 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;
}
}
㈡ ATM機取錢題的java做法
publicstaticvoidmain(String[]args){
StringrealPwd="111111";
IntegererrorCount=0;
Integeraccount;
Scannersc= newScanner(System.in);
while(true){
System.out.print("請輸入密碼：");
Stringpwd=sc.next();
if(!pwd.equals(realPwd)){
errorCount++;
System.out.println("第"+errorCount+"次輸入密碼不正確");
if(errorCount>=3){
System.out.println("密碼錯誤，請取卡");
break;
}
}else{
while(true){
System.out.print("請輸入取款金額：");
account=sc.nextInt();
if(account>1000||account<0){
System.out.println("取款金額最低0元，最高1000元");
}elseif(account%100!=0){
System.out.println("只有100的紙幣");
}else{
System.out.println("取款金額"+account+"元");
System.out.println("交易完成，請取卡");
break;
}
}
break;
}
}
}
㈢ 急急急~~求JAVA中用方法寫出一個銀行ATM取款機的代碼怎麼寫！！
public class Card {
public String type; //卡的類型
public String cardCode; //卡號
public double money; //錢
/**
* 重寫toString()方法
*/
public String toString(){
return "卡的類型："+type+"\t卡號："+cardCode+"\t余額："+money;
}
}public class Person {
Card card;
/**
* 構造方法，一般用來初始化信息
* 此方法是創建對象時自動調用的
*
*/
public Person(){
card=new Card();
card.type="招商銀行";
card.money=1000D;
}
/**
*
* @param money 你要取的錢
* @return 返回的是取到的錢
*/
public double getMoney(double money){
if( (card.money-money) >=0){
card.money=card.money-money;//從卡中減去要取的錢,並重新改變卡中的余額
return money;
}else{
System.out.println("余額不足:請存款！");
return 0;
}
}
/**
* 存款
* @param money
*/
public void setMoney(double money){
if(money<=0){
System.out.println("不能為0!");
}else
card.money=card.money+money;
}
/**
* 這個方法是輸出客戶卡的信息
*/
public void print(){
System.out.println(card);
}
}public class Text {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Person p=new Person();
p.card.cardCode="111100022222";
p.setMoney(1000);
double money=p.getMoney(2000);
System.out.println(p.card);
}
}
㈣ 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
㈤ ATM取款機系統用JAVA怎麼做/

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
