实验六：类的封装

一.实验程序如下

package fengzhuang;
import java.util.*;
public class Account {
public int Zhanghu;
public String Name;
public String Opentime;
public int Idcard;
public int Money;
public int Secret;

public Account(int Zhanghu, String Name,String Opentime,int Idcard, int Money,int Secret) {
    this.Zhanghu = Zhanghu;
    this.Name = Name;
    this.Opentime = Opentime;
    this.Idcard=Idcard;
    this.Money = Money;
    this.Secret=Secret;
}
public void kaihu(){
Scanner b=new Scanner(System.in);
System.out.println("请输入你的姓名:");
Name=b.next();
System.out.println("请输入你的身份账号：");
Idcard=b.nextInt();
System.out.println("请输入你的密码：");
Secret=b.nextInt();
System.out.println("用户开通账户成功！\n你的账户为"+Zhanghu);
}
//销户
public void xiaohu(){
Zhanghu=0;
Name="null";
Opentime="null";
Idcard=0;
Money=0;
Secret=0;
System.out.println("用户销户成功！");
}

public void Savemoney(){
while(true){
Scanner b=new Scanner(System.in);
System.out.println("请输入你的密码！");
int pass=b.nextInt();
if(pass==Secret){
System.out.println("请确认存钱的金额：");
int money=b.nextInt();
Money=Money+money;
break;
}else{
System.out.println("你输入的密码有错误，请重新进行操作;");
}
}
}

public void Takemoney (){
System.out.println("请输入需要取款的金额");
Scanner b=new Scanner(System.in);
int takemoney=b.nextInt();
if(takemoney<=Money){
Money=Money-takemoney;
}else{
System.out.println("当前余额不足");
}
}

public void Check(){
System.out.println("您的余额为"+Money);
}
//查询基本信息是在输入密码，密码正确的情况下才显示相应的信息
public void show(){
System.out.println("账户："+Zhanghu);
System.out.println("姓名："+Name);
}
public static void main(String[] args){
Scanner b=new Scanner(System.in);
Account a=new Account(20011,"张三","2005/12/3",00001,20000,123456789);
System.out.println("开通银行账户！");
System.out.println("****请输入你要执行的操作：*****");
System.out.println("****1-开户******");
System.out.println("*****2-查阅账号信息******");
System.out.println("*****3-存款******");
System.out.println("*****4-取款******");
System.out.println("*****5-查询余额******");
System.out.println("****6-销户******");

while(true)
{
int x=b.nextInt();
if(x==1||x==2||x==3||x==4||x==5||x==6||x==7){
switch(x){
case 1:
System.out.println("****开通账户*****");
a.kaihu();
break;
case 2:
System.out.println("****账号信息为*****");
a.show();
break;
case 3:
System.out.println("****进行存款****");
a.Savemoney();
break;
case 4:
System.out.println("进行取款*");
a.Takemoney();
break;
case 5:
a.Check();
break;
case 6:
a.xiaohu();
break;
case 7:
System.exit(0);
break;
}
}
else{
break;
}
}
}
}
