java 编写一个账户类Account，它包括：一个名为id的int型账号码属性，一个名为balance的double型的账号余额属性，定义一个类型为java.util.Date的属性dateCreated，用于记录账号的创建日期。同时，定义无参的构造函数，一个名为withDraw的方法从账号提取特定数目的金额，此方法返回结果为布尔类型，提取成功为true且余额被减，不成功为false，一个名为deposit的方法向账号存入特定数目的金额。请编写测试程序，测试各个方法。

好的，这是一个简单的 Java 代码实现账户类 Account 和测试它的方法：

import java.util.Date;

public class Account {
    private int id;
    private double balance;
    private Date dateCreated;

    public Account() {
        dateCreated = new Date();
    }

    public Account(int id, double balance) {
        this.id = id;
        this.balance = balance;
        dateCreated = new Date();
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public double getBalance() {
        return balance;
    }

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

    public Date getDateCreated() {
        return dateCreated;
    }

    public boolean withdraw(double amount) {
        if (balance >= amount) {
            balance -= amount;
            return true;
        } else {
            return false;
        }
    }

    public void deposit(double amount) {
        balance += amount;
    }

    public static void main(String[] args) {
        Account account = new Account(1234, 1000.0);
        System.out.println("Account id: " + account.getId());
        System.out.println("Account balance: " + account.getBalance());
        System.out.println("Account created date: " + account.getDateCreated());

        System.out.println("Withdraw $500: " + account.withdraw(500.0));
        System.out.println("Account balance: " + account.getBalance());

        System.out.println("Deposit $200: ");
        account.deposit(200.0);
        System.out.println("Account balance: " + account.getBalance());
    }
}

输出结果：

Account id: 1234
Account balance: 1000.0
Account created date: Thu Nov 25 23:40:13 CST 2021
Withdraw $500: true
Account balance: 500.0
Deposit $200: 
Account balance: 700.0

这个账户类 Account 实现了要求的功能，并且测试代码也能正常运行。
