java銀行系統設計與實現

① java編程簡單的銀行系統

public class Transation { private String tranType; // 定義交易類型
private String tranAccount; // 定義交易賬號
private double tranAmount; // 定義交易金額 public Transation(String tranType, String tranAccount, double tranAmount) { // 定義構造函數
this.tranAccount = tranAccount;
this.tranAmount = tranAmount;
this.tranType = tranType;
} //定義得到和設置屬性的方法
public String getTranType() {
return tranType;
} public void setTranType(String tranType) {
this.tranType = tranType;
} public String getTranAccount() {
return tranAccount;
} public void setTranAccount(String tranAccount) {
this.tranAccount = tranAccount;
} public double getTranAmount() {
return tranAmount;
} public void setTranAmount(double tranAmount) {
this.tranAmount = tranAmount;
}
}

② 用java語言編寫一個小型的銀行系統代碼

privateintbalance=0;

privateStringusername="A";
privateStringpassword="B";

publicvoidbank(){
Scannerscan=newScanner(System.in);
Stringtemp;

while(true){
System.out.println("輸入賬號：");

if(scan.hasNext()){
temp=scan.next();

if(temp.equals(username)){
break;
}else{
System.out.println("輸入錯誤");
}
}
}

while(true){
System.out.println("輸入密碼：");

if(scan.hasNext()){
temp=scan.next();

if(temp.equals(password)){
break;
}else{
System.out.println("輸入錯誤");
}
}
}

System.out.println("登錄成功");

while(true){
System.out.println("輸入操作：");

if(scan.hasNext()){
temp=scan.next();

switch(temp){
case"存款":
intx=0;

while(true){
System.out.println("輸入存款金額：");

if(scan.hasNextInt()){
x=scan.nextInt();

break;
}else{
System.out.println("輸入錯誤");

scan.next();
}
}

balance+=x;

break;
case"取款":
inty=0;

while(true){
System.out.println("輸入取款金額：");

if(scan.hasNextInt()){
y=scan.nextInt();

if(balance<y){
System.out.println("余額不足");

continue;
}

break;
}else{
System.out.println("輸入錯誤");

scan.next();
}
}

balance-=y;

break;
case"余額":
System.out.println("余額："+balance);

break;
case"終止":
System.exit(0);
default:
System.out.println("未知操作");
}
}
}

③ Java語言程序設計：設計銀行賬戶類，屬性包括賬號、儲戶名稱、開戶時間、身份證號碼、存款余額等

寫個例子吧，既沒有分，又不付費。。。。真的是。。
public class account{
public static int serviceNum;
private String account;
private String password;
......
public String getAccount(){
return this.account;
}
public void setAccount(String account){
this.account = account;
}
public String getPassword(){
return this.password;
}
public void setPassword(String password){
this.password = password
}
public Account(String account,String password){
this.account = account;
this.password = password;
}
public Account(String account){
this.account = account;
}
@overrite
public String toString(){
return this.account + "-" + this.password;
}
}

④ Java課程設計，模擬銀行存取業務，按照這個流程圖去做，其實最主要的是求畫圈的部分怎麼寫和它的方法。

請點擊輸入圖片描述

package com.greatwall.business.controller;

import java.math.BigDecimal;

import java.util.Scanner;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class BankTest {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

// 余額（單位：分）

Long BALANCE = 10000000L;

// 卡號

String card = "001";

// 密碼

String password = "123456";

String inputCard = new String();

String inputPassword = new String();

String quit = new String();

while (true) {

System.out.println(" 歡迎來到網上銀行辦理存取款業務！");

System.out.println("請輸入銀行卡號和銀行卡密碼進行登錄！");

while (true) {

System.out.print("請輸入銀行卡號(按q退出): ");

inputCard = scan.nextLine();

quit = inputCard;

if (inputCard.equals("q")) {

break;

}

if (!inputCard.equals(card)) {

System.out.print("您輸入銀行卡號不正確，請重新輸入 ");

continue;

}

break;

}

if (quit.equals("q")) {

continue;

}

while (true) {

System.out.print("請輸入銀行卡密碼(按q退出): ");

inputPassword = scan.nextLine();

quit = inputPassword;

if (inputPassword.equals("q")) {

break;

}

if (!inputPassword.equals(password)) {

System.out.print("您輸入銀行卡密碼不正確，請重新輸入 ");

continue;

}

break;

}

if (quit.equals("q")) {

continue;

}

System.out.print("登錄成功，當前登錄的賬戶名:" + inputCard);

String type = "4";

while (!type.equals("0")) {

System.out.print(" 您當前的余額為：" + money(BALANCE) + "元");

System.out.print(" 請選擇操作類型。（存款：1；取款：2 ；余額：3；退出：0） ");

type = scan.nextLine();

switch (type) {

case "1": {

System.out.print("請輸入您的存款金額(元)：");

String chageNumber = scan.nextLine();

if (!isPositiveInteger(chageNumber)) {

System.out.print("請輸入正確的存款金額！");

continue;

}

BALANCE = Long.valueOf(chageNumber) * 100 + BALANCE;

continue;

}

case "2": {

System.out.print("請輸入您的取款金額(元)：");

String chageNumber = scan.nextLine();

if (!isPositiveInteger(chageNumber)) {

System.out.print("請輸入正確取款金額！");

continue;

}

BALANCE = BALANCE - Long.valueOf(chageNumber) * 100;

continue;

}

case "3": {

System.out.print("您當前的余額為：" + money(BALANCE) + "元 ");

continue;

}

default: {

continue;

}

}

}

}

}

private static boolean isMatch(String regex, String orginal) {

if (orginal == null || orginal.trim().equals("")) {

return false;

}

Pattern pattern = Pattern.compile(regex);

Matcher isNum = pattern.matcher(orginal);

return isNum.matches();

}

// 判斷數據是否為正整數

public static boolean isPositiveInteger(String orginal) {

return isMatch("^\+{0,1}[1-9]\d*", orginal);

}

// 分轉元，轉換為bigDecimal在toString

public static String money(Long money) {

return BigDecimal.valueOf(money).divide(new BigDecimal(100)).toString();

}

}

⑤ 用Java編寫簡單的銀行系統

這個有點復雜，說點簡單的思路
1.首先要建立資料庫表，保存數據需要保存到表中專
create table Account(
賬號屬ID
密碼
有多少錢
)

如果要保存流水記錄的話，還的建張表保存記錄

2.java
賬號類
class Account{
賬號ID
密碼
有多少錢
}

一個操作類
class Test{
開戶，登錄，存款，取款，查詢余額，修改密碼
各寫一個方法
}

⑥ 用JAVA編程設計一個銀行賬戶類，其中包括以下內容，並用字元界面模擬存款和取款過程。

import java.util.Scanner;

public class ZH {

private String zh;//賬戶
private String password;//密碼
private String openTime;//開戶時間
private String sfz;//身份證號
private double je;//存款金額
public String getZh() {
return zh;
}
public void setZh(String zh) {
this.zh = zh;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getOpenTime() {
return openTime;
}
public void setOpenTime(String openTime) {
this.openTime = openTime;
}
public String getSfz() {
return sfz;
}
public void setSfz(String sfz) {
this.sfz = sfz;
}
public double getJe() {
return je;
}
public void setJe(double je) {
this.je = je;
}

//存款方法
public void ck(double je){
this.je=this.je+je;//存入的金額加上原有的金額
}

//取款方法
public void qk(double je){
if(je>this.je){//取款金額大於余額
System.out.println("存款余額不足");
}else{
this.je=this.je-je;//原有的金額減去取出的金額
}
}
public static void main(String[] args) {
ZH zh = new ZH();//初始化一個賬戶信息
zh.setJe(10000.0);//向zh賬戶添加余額
zh.setOpenTime("2013.12.3");//向zh賬戶添加開發時間
zh.setPassword("123456");//向zh賬戶添加密碼
zh.setSfz("123456789");//向zh賬戶添加身份證
zh.setZh("zhangsan");//向zh賬戶添加賬號
System.out.println("歡迎光臨模擬銀行");
Scanner scan = new Scanner(System.in);
int count=0;//記錄輸入錯誤的次數
while(1==1){//循環
System.out.println("請輸入賬號");
String zhm=scan.next();
System.out.println("請輸入密碼");
String mm=scan.next();
if(zhm.equals(zh.getZh()) && mm.equals(zh.getPassword())){//輸入的信息與zh賬戶信息的密碼和賬號一致
while(1==1){
System.out.println("當前余額為："+zh.getJe()+"元。請選擇操作：1.存款；2.取款；3.退出（只能輸入數字）");
String cz=scan.next();
switch (Integer.parseInt(cz)) {
case 1:
System.out.println("請輸入存款金額（輸入小數）");
double ckje=scan.nextDouble();
zh.ck(ckje);
System.out.println("實施存款："+ckje+"元，當前余額為"+zh.getJe()+"元");
break;
case 2:
System.out.println("請輸入取款金額（輸入小數）");
double qkje=scan.nextDouble();
zh.qk(qkje);
System.out.println("實施取款："+qkje+"元，當前余額為"+zh.getJe()+"元");
break;
case 3:
break;
default:
System.out.println("暫無此功能");//輸入1或者2、3以外的操作
break;
}
if("3".equals(cz)){
break;
}
}
System.out.println("退出操作");
break;
}else{

if(count>=3){
System.out.println("已輸入錯誤三次，賬號被鎖");
break;//結束循環
}else{
System.out.println("賬號或密碼錯誤，請重新輸入");
count++;//錯誤一次count+1
continue;//進入下次循環
}
}
}

}
}

⑦ JAVA 簡單銀行系統的代碼

這個不簡單，
從分析設計，到編碼實現，
都是需要精力和時間花費的體現，
建議還是自己親自走一遍吧，
能學點東西。
