银行存款问题

有两个人给一个银行账户存款，每个人分别存入3000元，一次存1000，分别存三次

package com.atguigu.exer;

import java.util.concurrent.locks.ReentrantLock;

class Account{
   private double banlance=0;
//存钱
    public void  subBanlance(double banlance) throws InterruptedException {
        Thread.sleep(1000);
        this.banlance += banlance;
    }

    public double getBanlance() {
        return banlance;
    }
}
//继承的方式
class Customer extends  Thread{
    private Account account;
    private static ReentrantLock lock=new ReentrantLock(true);//保证同一个锁
    public Customer(Account a){
        this.account=a;
    }

    @Override
    public void run() {
        for(int i=0;i<3;i++) {
            try {
                lock.lock();

                //synchronized (Customer.class) {
                try {

                    e.printStackTrace();
                }
                System.out.println(Thread.currentThread().getName() + "存入1000元，当前账户余额为" + account.getBanlance());

                lock.unlock();
            }
        }
    }

//接口的方式
