用java写模拟一个简单的银行系统,使用两个不同的线程向同一个账户存钱。 账户的初始余额是1000元，两个线程每次存储100元,分别各存储1000元，不允许出现错误数据。 程序运行结果如下图所示：不要求轮流存

以下是一个简单的Java代码实现，使用了同步锁来保证线程安全：

class Bank {
    private int balance = 1000;

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

class DepositThread implements Runnable {
    private Bank bank;

    public DepositThread(Bank bank) {
        this.bank = bank;
    }

    public void run() {
        for (int i = 0; i < 10; i++) {
            bank.deposit(100);
        }
    }
}

public class BankSystem {
    public static void main(String[] args) {
        Bank bank = new Bank();
        Thread thread1 = new Thread(new DepositThread(bank));
        Thread thread2 = new Thread(new DepositThread(bank));
        thread1.start();
        thread2.start();
    }
}

输出结果：

Deposit 100, current balance is 1100
Deposit 100, current balance is 1200
Deposit 100, current balance is 1300
Deposit 100, current balance is 1400
