java银行管理系统源码

java银行管理系统源码

银行管理系统 (java实现)，供大家参考，具体内容如下

1.创建一个封装类（Studentss）

import javax.naming.Name;

import javax.naming.NamingEnumeration;

public class Studentss {

//无参

public Studentss(){}

//有参

public Studentss(String name,String account,int balance,String uesrpwds,String card){

super();

this.name=name;

this.account=account;

this.balance=balance;

this.uesrpwds=uesrpwds;

this.card=card;

}

//修改

public Studentss(String name,String account,int balance,String uesrpwds,String card,int id){

super();

this.name=name;

this.account=account;

this.balance=balance;

this.uesrpwds=uesrpwds;

this.card=card;

this.id = id;

}

//定义一个数据类封装

private String name;//名字

private String account;//账号

private int balance;//余额

private String uesrpwds;//密码

private String card;//身份证号

private int id;//编号

//封装id

public int getId(){

return id;

}

public void setId(int id) {

this.id = id;

}

//封装名字get

public String getName(){

return name;

}

public void setName(String name) {

this.name = name;

}

//封装账号get

public String getAccount(){

return account;

}

public void setAccount(String account) {

this.account = account;

}

//封装余额get

public int getBalance() {

return balance;

}

public void setBalance(int balance) {

this.balance = balance;

}

//封装密码get

public String getUesrpwds() {

return uesrpwds;

}

public void setUesrpwds(String uesrpwds) {

this.uesrpwds = uesrpwds;

}

//封装身份证get

public String getCard() {

return card;

}

//set身份证

public void setCard(String card) {

this.card = card;

}

@Override

public String toString() {

return super.toString();

}

}

2.实现增删改查等效果 main方法(DoemTest)

import com.sun.org.apache.xpath.internal.objects.XObject;

import java.util.ArrayList;

import jtoDrVZdava.util.Iterator;

import java.util.List;

import java.util.Scanner;

public class DoemTest{

public static ArrayList list =new ArrayList<>();//声明数组

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

//初始化两个数据

Studentss studentss = new Studentss();

studentss.setName("张颖颖");

studentss.setAccount("17908064359");

shttp://tudentss.setBalance(2000);

studentss.setUesrpwds("4321");

studentss.setCard("510010619891231127");

list.add(studentss);//初始化数组 添加值

Studentss studentss1 = new Studentss();

studentss1.setName("刘华");

studentss1.setAccount("17908064368");

studentss1.setBalance(8000);

studentss1.setUesrpwds("4567");

studentss1.setCard("410207198904051271");

list.add(studentss1);//初始化数组 添加值

// this.list =new ArrayList<>();

//String pass =input.lenth();

int input;

//银行增删改查输出

System.out.println("账户姓名:张颖颖 账号: 17908064359 存款余额: 2000 密码：4321 身份证号:510010619891231127");

System.out.println("账户姓名:刘华 账号: 17908064368 存款余额: 8000 密码：4567 身份证号:410207198904051271");

do {

System.out.println("=====================欢迎使用知道银行服务====================");

System.out.println("1:开户 2:存款 3: 取款 4: 转账 5:查余额 6:修改密码 0:退出");

System.out.println("===========================================================");

//判断输出选项

注：(我的代码可以有些的纰漏，问题不是很大，基本逻辑写的差不多了，如果有问题，评论下，我虚心请教，希望我们的代码之路会越走越远！加油)
