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）
importjavax.naming.Name;
importjavax.naming.NamingEnumeration;
publicclassStudentss{
//无参
publicStudentss(){}
//有参
publicStudentss(Stringname,Stringaccount,intbalance,Stringuesrpwds,Stringcard){
super();
this.name=name;
this.account=account;
this.balance=balance;
this.uesrpwds=uesrpwds;
this.card=card;
}
//修改
publicStudentss(Stringname,Stringaccount,intbalance,Stringuesrpwds,Stringcard,intid){
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
privateStringname;//名字
privateStringaccount;//账号
privateintbalance;//余额
privateStringuesrpwds;//密码
privateStringcard;//身份证号
privateintid;//编号
//封装id
publicintgetId(){
returnid;
}
publicvoidsetId(intid){
this.id=id;
}
//封装名字get
publicStringgetName(){
returnname;
}
publicvoidsetName(Stringname){
this.name=name;
}
//封装账号get
publicStringgetAccount(){
returnaccount;
}
publicvoidsetAccount(Stringaccount){
this.account=account;
}
//封装余额get
publicintgetBalance(){
returnbalance;
}
publicvoidsetBalance(intbalance){
this.balance=balance;
}
//封装密码get
publicStringgetUesrpwds(){
returnuesrpwds;
}
publicvoidsetUesrpwds(Stringuesrpwds){
this.uesrpwds=uesrpwds;
}
//封装身份证get
publicStringgetCard(){
returncard;
}
//set身份证
publicvoidsetCard(Stringcard){
this.card=card;
}
@Override
publicStringtoString(){
returnsuper.toString();
}
}
2.实现增删改查等效果main方法(DoemTest)
importcom.sun.org.apache.xpath.internal.objects.XObject;
importjava.util.ArrayList;
importjava.util.Iterator;
importjava.util.List;
importjava.util.Scanner;
publicclassDoemTest{
publicstaticArrayListlist=newArrayList<>();//声明数组
publicstaticvoidmain(String[]args){
Scannersc=newScanner(System.in);
//初始化两个数据
Studentssstudentss=newStudentss();
studentss.setName("张颖颖");
studentss.setAccount("17908064359");
studentss.setBalance(2000);
studentss.setUesrpwds("4321");
studentss.setCard("510010619891231127");
list.add(studentss);//初始化数组添加值
Studentssstudentss1=newStudentss();
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=newArrayList<>();
//Stringpass=input.lenth();
intinput;
//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("===========================================================");

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)
