写一个名为Account的类模拟账户。该类的属性和方法如下图所示。该类包括的属性：账号id，余额balance，年利率annualInterestRate；包含的方法：访问器方法（getter和setter方法），返回月利率的方法getMonthlyInterest()，取款方法withdraw()，存款方法deposit Java代码

以下是使用Java语言实现的`Account`类的代码示例：

class Account {
    private int accountId;
    private double balance;
    private double annualInterestRate;

    public Account(int accountId, double balance, double annualInterestRate) {
        this.accountId = accountId;
        this.balance = balance;
        this.annualInterestRate = annualInterestRate;
    }

    public int getAccountId() {
        return accountId;
    }

    public void setAccountId(int accountId) {
        this.accountId = accountId;
    }

    public double getBalance() {
        return balance;
    }

    public void setBalance(double balance) {
        this.balance = balance;
    }

    public double getAnnualInterestRate() {
        return annualInterestRate;
    }

    public void setAnnualInterestRate(double annualInterestRate) {
        this.annualInterestRate = annualInterestRate;
    }

    public double getMonthlyInterest() {
        return balance * (annualInterestRate / 12);
    }

    public void withdraw(double amount) {
        if (amount <= balance) {
            balance -= amount;
            System.out.println("成功取出：" + amount + "元");
        } else {
            System.out.println("余额不足，取款失败");
        }
    }

    public void deposit(double amount) {
        balance += amount;
        System.out.println("成功存入：" + amount + "元");
    }
}

public class Main {
    public static void main(String[] args) {
        Account account = new Account(123456, 1000.0, 0.05);
        
        System.out.println("账户ID：" + account.getAccountId());
        System.out.println("当前余额：" + account.getBalance());
        System.out.println("月利率：" + account.getMonthlyInterest());

        account.withdraw(500);
        System.out.println("当前余额：" + account.getBalance());

        account.deposit(200);
        System.out.println("当前余额：" + account.getBalance());
    }
}

以上代码定义了一个`Account`类，包括账号ID、余额和年利率等属性。该类提供了相应的访问器方法（getter和setter方法）以及返回月利率、取款和存款等方法。

在`Main`类的`main`方法中，创建了一个`Account`对象，并通过访问器方法获取和设置属性值。然后调用取款和存款方法来模拟账户的操作，并输出相应的结果。
