java银行系统设计与实现

① java编程简单的银行系统

public class Transation { private String tranType; // 定义交易类型
private String tranAccount; // 定义交易账号
private double tranAmount; // 定义交易金额 public Transation(String tranType, String tranAccount, double tranAmount) { // 定义构造函数
this.tranAccount = tranAccount;
this.tranAmount = tranAmount;
this.tranType = tranType;
} //定义得到和设置属性的方法
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语言编写一个小型的银行系统代码

privateintbalance=0;

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

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

while(true){
System.out.println("输入账号：");

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

if(temp.equals(username)){
break;
}else{
System.out.println("输入错误");
}
}
}

while(true){
System.out.println("输入密码：");

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

if(temp.equals(password)){
break;
}else{
System.out.println("输入错误");
}
}
}

System.out.println("登录成功");

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

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

switch(temp){
case"存款":
intx=0;

while(true){
System.out.println("输入存款金额：");

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

break;
}else{
System.out.println("输入错误");

scan.next();
}
}

balance+=x;

break;
case"取款":
inty=0;

while(true){
System.out.println("输入取款金额：");

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

if(balance<y){
System.out.println("余额不足");

continue;
}

break;
}else{
System.out.println("输入错误");

scan.next();
}
}

balance-=y;

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

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

③ Java语言程序设计：设计银行账户类，属性包括账号、储户名称、开户时间、身份证号码、存款余额等

写个例子吧，既没有分，又不付费。。。。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课程设计，模拟银行存取业务，按照这个流程图去做，其实最主要的是求画圈的部分怎么写和它的方法。

请点击输入图片描述

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);

// 余额（单位：分）

Long BALANCE = 10000000L;

// 卡号

String card = "001";

// 密码

String password = "123456";

String inputCard = new String();

String inputPassword = new String();

String quit = new String();

while (true) {

System.out.println(" 欢迎来到网上银行办理存取款业务！");

System.out.println("请输入银行卡号和银行卡密码进行登录！");

while (true) {

System.out.print("请输入银行卡号(按q退出): ");

inputCard = scan.nextLine();

quit = inputCard;

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

break;

}

if (!inputCard.equals(card)) {

System.out.print("您输入银行卡号不正确，请重新输入 ");

continue;

}

break;

}

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

continue;

}

while (true) {

System.out.print("请输入银行卡密码(按q退出): ");

inputPassword = scan.nextLine();

quit = inputPassword;

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

break;

}

if (!inputPassword.equals(password)) {

System.out.print("您输入银行卡密码不正确，请重新输入 ");

continue;

}

break;

}

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

continue;

}

System.out.print("登录成功，当前登录的账户名:" + inputCard);

String type = "4";

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

System.out.print(" 您当前的余额为：" + money(BALANCE) + "元");

System.out.print(" 请选择操作类型。（存款：1；取款：2 ；余额：3；退出：0） ");

type = scan.nextLine();

switch (type) {

case "1": {

System.out.print("请输入您的存款金额(元)：");

String chageNumber = scan.nextLine();

if (!isPositiveInteger(chageNumber)) {

System.out.print("请输入正确的存款金额！");

continue;

}

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

continue;

}

case "2": {

System.out.print("请输入您的取款金额(元)：");

String chageNumber = scan.nextLine();

if (!isPositiveInteger(chageNumber)) {

System.out.print("请输入正确取款金额！");

continue;

}

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

continue;

}

case "3": {

System.out.print("您当前的余额为：" + 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();

}

// 判断数据是否为正整数

public static boolean isPositiveInteger(String orginal) {

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

}

// 分转元，转换为bigDecimal在toString

public static String money(Long money) {

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

}

}

⑤ 用Java编写简单的银行系统

这个有点复杂，说点简单的思路
1.首先要建立数据库表，保存数据需要保存到表中专
create table Account(
账号属ID
密码
有多少钱
)

如果要保存流水记录的话，还的建张表保存记录

2.java
账号类
class Account{
账号ID
密码
有多少钱
}

一个操作类
class Test{
开户，登录，存款，取款，查询余额，修改密码
各写一个方法
}

⑥ 用JAVA编程设计一个银行账户类，其中包括以下内容，并用字符界面模拟存款和取款过程。

import java.util.Scanner;

public class ZH {

private String zh;//账户
private String password;//密码
private String openTime;//开户时间
private String sfz;//身份证号
private double je;//存款金额
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;//存入的金额加上原有的金额
}

//取款方法
public void qk(double je){
if(je>this.je){//取款金额大于余额
System.out.println("存款余额不足");
}else{
this.je=this.je-je;//原有的金额减去取出的金额
}
}
public static void main(String[] args) {
ZH zh = new ZH();//初始化一个账户信息
zh.setJe(10000.0);//向zh账户添加余额
zh.setOpenTime("2013.12.3");//向zh账户添加开发时间
zh.setPassword("123456");//向zh账户添加密码
zh.setSfz("123456789");//向zh账户添加身份证
zh.setZh("zhangsan");//向zh账户添加账号
System.out.println("欢迎光临模拟银行");
Scanner scan = new Scanner(System.in);
int count=0;//记录输入错误的次数
while(1==1){//循环
System.out.println("请输入账号");
String zhm=scan.next();
System.out.println("请输入密码");
String mm=scan.next();
if(zhm.equals(zh.getZh()) && mm.equals(zh.getPassword())){//输入的信息与zh账户信息的密码和账号一致
while(1==1){
System.out.println("当前余额为："+zh.getJe()+"元。请选择操作：1.存款；2.取款；3.退出（只能输入数字）");
String cz=scan.next();
switch (Integer.parseInt(cz)) {
case 1:
System.out.println("请输入存款金额（输入小数）");
double ckje=scan.nextDouble();
zh.ck(ckje);
System.out.println("实施存款："+ckje+"元，当前余额为"+zh.getJe()+"元");
break;
case 2:
System.out.println("请输入取款金额（输入小数）");
double qkje=scan.nextDouble();
zh.qk(qkje);
System.out.println("实施取款："+qkje+"元，当前余额为"+zh.getJe()+"元");
break;
case 3:
break;
default:
System.out.println("暂无此功能");//输入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("已输入错误三次，账号被锁");
break;//结束循环
}else{
System.out.println("账号或密码错误，请重新输入");
count++;//错误一次count+1
continue;//进入下次循环
}
}
}

}
}

⑦ JAVA 简单银行系统的代码

这个不简单，
从分析设计，到编码实现，
都是需要精力和时间花费的体现，
建议还是自己亲自走一遍吧，
能学点东西。

⑧ 用java实现银行排队程序，要求模拟银行的业务排队系统，要有界面，实现完成的排队和叫号
