這篇文章主要為大家詳細(xì)介紹了java銀行管理系統(tǒng)源碼，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

銀行管理系統(tǒng) (java實(shí)現(xiàn))，供大家參考，具體內(nèi)容如下

1.創(chuàng)建一個(gè)封裝類（Studentss）

import javax.naming.Name;

import javax.naming.NamingEnumeration;
 
 public class Studentss {

//無(wú)參
public Studentss(){}
//有參
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;
}

//定義一個(gè)數(shù)據(jù)類封裝
private String name;//名字
private String account;//賬號(hào)
private int balance;//余額
private String uesrpwds;//密碼
private String card;//身份證號(hào)
private int id;//編號(hào)
//封裝id
public int getId(){
 return id;
}

public void setId(int id) {
 this.id = id;
}
//封裝名字get
public String getName(){
 return name;
}

 public void setName(String name) {
 this.name = name;
}

//封裝賬號(hào)get
public String getAccount(){
 return account;
}

public void setAccount(String account) {
 this.account = account;
}

//封裝余額get

public int getBalance() {
 return balance;
}

public void setBalance(int balance) {
 this.balance = balance;
}
//封裝密碼get
public String getUesrpwds() {
 return uesrpwds;
}
public void setUesrpwds(String uesrpwds) {
 this.uesrpwds = uesrpwds;
}
//封裝身份證get
public String getCard() {
 return card;
}
//set身份證
public void setCard(String card) {
 this.card = card;
}


@Override
public String toString() {
 return super.toString();
}
}

2.實(shí)現(xiàn)增刪改查等效果 main方法(DoemTest)

 list.add(studentss1);//初始化數(shù)組 添加值
 // this.list =new ArrayList<>();
 //String pass =input.lenth();
 int input;
 //銀行增刪改查輸出

 System.out.println("賬戶姓名:張穎穎 賬號(hào): 17908064359 存款余額: 2000 密碼：4321 身份證號(hào):510010619891231127");
