案例介绍：

定义一个名为Account的类实现账户管理，它的UML图如下图所示：
在这里插入图片描述

编写一个应用程序测试Account的类的使用。

案例代码：

import java.util.Date;
public class Account{
    private int id;    
    private double balance;
    private double annulInterestRate;
    private Date dateCreated;
    public Account(){
        super();
    }
    public Account(int id, double balance){
    super();
    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 double getAnnulInterestRate(){
        return annulInterestRate;
    } 
    public void setAnnulInterestRate(double annulInterestRate){
        this.annulInterestRate = annulInterestRate;
    }
    public Date getDateCreated(){
        return dateCreated;
    }
    public void withdraw(double amount){
        balance = balance - amount;
    }
    public void deposit(double amount){
        balance = balance + amount;
    }
    public static void main( String[ ] args){
        Account myAccount = new Account( 101,1000.00);
        myAccount.deposit( 100);
        myAccount.withdraw( 200) ;
        System.out.println("The balance = " + myAccount.getBalance());
    }
}
