java編寫atm

1. atm機的java怎麼寫啊

package demo;
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

/********************/
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;
}

return name;
}

}

}

/*得到剩餘的錢的數目*/

}
}
/**********實現具體取款機功能*********/

Welcome();
SysOpter();
}

atm.Load_Sys();
// atm.Exit_Sys();
}
}

卡號：00000 密碼123456 默認50000金額。簡單版本的存取款。

2. java atm機代碼

package arraylist;

import java.util.Scanner;

public class AtmDemo
{

public static void main(String[] args)
{
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
Boolean flag = true;
int times = 0;
while(flag){
times++;
if(times == 4){
System.out.println("密碼錯誤，請取卡");
break;
}
System.out.println("請輸入你的密碼");
String password = sc.next();

if(password.equals("111111")){
Boolean moneyflag = true;
while(moneyflag){
System.out.println("請輸入金額");
int number = sc.nextInt();
if(number >= 0 && number <= 1000 && number % 100 == 0){
System.out.println("用戶取了" + number + "元。交易完成");
moneyflag = false;
}else{
System.out.println("請重新輸入金額");
}
}
break;
}else{
continue;
}

}
}

}

3. 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);
}
}

}
}

4. 用java做一個簡易的ATM機具體流程在下面

代碼如下

packageBaiD;

importjava.util.Scanner;

publicclassATM{
	/*1提示請輸入密碼然後直接進入下一步。密碼6位限制（限制方法用「最小大於100000最大小於999999」這樣限制）
	2.提示密碼正確還是錯誤密碼直接弄成「123456」錯誤返回上一步循環方法用for循環。
	3.密碼輸入正確後進入下一步提示5個選項（1.余額查詢「基礎10000」2.取款3存款4.退出）
	4.進行取款或者存款之後要回到第三步重新選擇（余額和取款存款相關聯）
	備註：用鍵盤輸入的方法用scanner*/
	
	privatestaticintmoney=10000;//全局變數余額默認10000
publicstaticvoidmain(Stringargs[])
{
	for(;;){//for循環，有意思嗎？
System.out.println("請輸入密碼：");
	Scannerinput=newScanner(System.in);
	intpw=input.nextInt();
	if(Checkpw(pw)){
		System.out.println("密碼正確。");
		Next();
	}
		
	elseSystem.out.println("密碼錯誤！");
	}
	
}
publicstaticbooleanCheckpw(intpw)
{
	if(pw==123456)returntrue;//固定密碼就不需要限制位數了，反正不符合就錯
	else
	returnfalse;
}

	publicstaticvoidNext(){
		do{		
		System.out.println("請選擇你需要的功能：");
		System.out.println("1.余額查詢2.取款3.存款4.退出");
		intvalue=newScanner(System.in).nextInt();
		switch(value){
		case1://查詢余額
			System.out.println("您的余額為"+money+"元");
			break;
		case2://取款
			System.out.println("請輸入取款金額:");
			
			intgetnum=newScanner(System.in).nextInt();
			if(getnum<0)System.out.println("輸入金額有誤!");
			elseif(getnum>money)System.out.println("余額不足.");
			else{money=money-getnum;System.out.println("取款成功,余額為"+money);}			

			break;
		case3://存款
			System.out.println("請輸入存款金額:");
			
			intpushnum=newScanner(System.in).nextInt();
			if(pushnum<0)System.out.println("輸入金額有誤!");
			else{money=money+pushnum;System.out.println("存款成功，余額為"+money);}	
			break;
		case4://退出
			System.out.println("謝謝使用！");
			System.exit(0);
			break;
		
		default:
			
			System.out.println("輸入有誤");
			break;
		}
		
		
	}while(true);
		}

}

2、運行效果

5. 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();
}
}
}
}

6. 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;
}

}

}

}
