2.线程任务类：主要用来模拟和用户的交互，两个while循环来模拟登录/注册操作和存取款操作，用用户的卡号作为文件名，创建文件，并利用io流将对象写入文件，保存此账户类。注册后登录，校验用户输入的账号密码和文件中存储的是否一致。
package allclass;
import java.io.*;
import java.util.Scanner;
public class UserAccess implements Runnable {
@Override
public void run() {
boolean usestatus=true;
Scanner userinput=new Scanner(System.in);
while(usestatus){
System.out.println("登录请按1"+"n"+"注册请按2"+"n"+"退出请按3");
String options123=userinput.next();
//用户登录；
System.out.println("正常输入");
if(options123.equals("1")){
System.out.println("请输入卡号：");
String userid=userinput.next();
System.out.println("请输入密码：");
String userpassword=userinput.next();
ObjectInputStream in = null;
try {
//获取密码，匹配密码；
in = new ObjectInputStream(new FileInputStream("userdata\"+userid));
Account user=(Account) in.readObject();
in.close();
if (user.matchpassword(userpassword)){
System.out.println("登陆成功");
user.setUserstatus(true);
//标记账号为登录状态，并且开始执行用户操作。
ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("userdata\"+userid));
while(user.getUserstatus()){
System.out.println("存钱请按------>1"+"n"+"取钱请按------>2"+"n"+"修改密码请按--->3"+"n"+"余额查询请按--->4n"+"推出请按------>5");
String useraction123=userinput.next();
if (useraction123.equals("1")){
System.out.println("请输入存入数额（元）:");
double savemoney=userinput.nextDouble();
user.setSurplus(user.getSurplus()+savemoney);
System.out.println("存钱成功");
}
else if(useraction123.equals("2")){
System.out.println("请输入取款数额（元）:");
double takemoney=userinput.nextDouble();
user.setSurplus(user.getSurplus()-takemoney);
System.out.println("取款成功");
}
else if (useraction123.equals("3")){
System.out.println("请输入新密码:");
String newpassword=userinput.next();
user.setPassword(newpassword);
System.out.println("修改成功");
}
else if (useraction123.equals("5")){
user.setUserstatus(false);
}
else{
System.out.println(user.getSurplus());
}
}
out.writeObject(user);
out.close();
}
else{
continue;
}
} catch (Exception e) {
e.printStackTrace();
}
}
//用户注册；
else if(options123.equals("2")){
System.out.println("请设置卡号：");
String userid=userinput.next();
System.out.println("请设置密码：");
String userpassword=userinput.next();
Account newuser=new Account(userid,userpassword);
try {
ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("userdata\"+userid));
out.writeObject(newuser);
System.out.println("注册成功，请牢记您的账号密码！");
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
//退出；
else{
usestatus=false;
continue;
}
}
}
}
3.主类：将任务线程放入线程池，开始运行线程。
package allclass;
import java.util.Timer;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
public class AtuoBank {
public static void main(String[] args){
ExecutorService atm=new ThreadPoolExecutor(1,2,3, TimeUnit.DAYS,new ArrayBlockingQueue<>(5));
UserAccess zxr=new UserAccess();
atm.execute(zxr);
}
}
