用java写一个多线程实现银行存取款系统并且写两名顾客，每人分三次、每次100元将钱汇入count。 每进行一次汇款，便输出汇款人和账户总额。

下面是一个使用Java多线程实现银行存取款系统并且包括两名顾客的示例代码：

public class BankAccount {
    private int balance;

    public BankAccount(int initialBalance) {
        this.balance = initialBalance;
    }

    public synchronized void deposit(int amount) {
        balance += amount;
        System.out.println("Deposited " + amount + "; balance is now " + balance);
    }

    public synchronized void withdraw(int amount) {
        if (balance >= amount) {
            balance -= amount;
            System.out.println("Withdrew " + amount + "; balance is now " + balance);
        } else {
            System.out.println("Insufficient funds");
        }
    }

    public int getBalance() {
        return balance;
    }
}

public class BankTransaction implements Runnable {
    private BankAccount account;
    private int amount;
    private boolean deposit;
    private String customerName;

    public BankTransaction(BankAccount account, int amount, boolean deposit, String customerName) {
        this.account = account;
        this.amount = amount;
        this.deposit = deposit;
        this.customerName = customerName;
    }

    public void run() {
        if (deposit) {
            account.deposit(amount);
        } else {
            account.withdraw(amount);
        }
        System.out.println(customerName + " balance is now " + account.getBalance());
    }
}

public class BankDemo {
    public static void main(String[] args) {
        BankAccount account = new BankAccount(0);

        Thread t1 = new Thread(new BankTransaction(account, 100, true, "Customer 1"));
        Thread t2 = new Thread(new BankTransaction(account, 100, true, "Customer 2"));
        Thread t3 = new Thread(new BankTransaction(account, 100, true, "Customer 1"));
        Thread t4 = new Thread(new BankTransaction(account, 100, true, "Customer 2"));
        Thread t5 = new Thread(new BankTransaction(account, 100, true, "Customer 1"));
        Thread t6 = new Thread(new BankTransaction(account, 100, true, "Customer 2"));

        t1.start();
        t2.start();
        t3.start();
        t4.start();
        t5.start();
        t6.start();
    }
}

该示例中，`BankAccount` 类表示银行账户，包含一个账户余额变量和 `deposit` 和 `withdraw` 方法用于存款和取款。这两个方法都使用 `synchronized` 关键字来确保在多线程环境下的安全性。

`BankTransaction` 类实现了 `Runnable` 接口，表示银行交易，其中包含一个银行账户、一个交易金额、一个布尔值表示是否为存款，以及一个字符串表示顾客姓名。`run` 方法根据布尔值调用 `deposit` 或 `withdraw` 方法，并在执行完交易后输出顾客姓名和账户余额。

`BankDemo` 类用于演示多线程银行存取款系统，并包括两名顾客。在主函数中创建一个 `BankAccount` 对象和六个 `BankTransaction` 对象，每个顾客分别进行三次存款，每次存款 100 元。在每次存款后，输出顾客姓名和账户余额。在运行过程中，`BankAccount` 的 `deposit` 和 `withdraw` 方法将确保多线程环境下的数据安全。
