工厂模式 - 程序实现(java)

    09年5月CSDN一网友提出如下问题:

设计一个用于管理银行客户的类BankCustomer:
	仅描述客户的几个重要方面:
		帐号、身份证号、姓名、联系方式、密码、账户余额。
	所有的成员变量均用private访问控制,因此每一个成员变量就要有相应的存取器
	(getter和setter,即获取和设置其值的相应的成员方法。需要setter还是getter,还是两者都要,视情况而定)

	成员方法:
	开户(开户时必须要有身份证号),系统自动生成帐号,帐号使用系统时间(格式:"yyyyMMddHHmmss"14位),初始密码为“666666”。
	注意开户和构造方法之间的关系。
	存钱、取钱、显示账户信息、修改密码(密码最短要六位)
	怎样在main中使用这个类,自行安排,要表现出你设计的类的各个方面,并在main中用英语加以注释 

    根据此,使用工厂模式设计如下若干类:

    ------------factory部分---------------------------xiaobin-------------

    Customer:        抽象类(factory祖先类)

    BankCustomer:继承类(factory类)

   

    〉〉〉〉〉〉〉〉〉〉扩展部分

    ContactWay:联系方式(factory引用类)

    IM                :实时消息(ContactWay引用类)

    ------------product部分---------------------------xiaobin-------------   
    Bank:            接口(product接口)

    Account:       实现类(concrete product类)

 

   类图如下:(使用Enterprise Architect绘制)

                           

 

 

 

   使用EA生成的代码如下:

   Customer.java

package bankCustomer;

/**

	private Bank bank;
	private double myMoney;
	public Bank m_Bank;

	public Customer(){

	}

	public void finalize() throws Throwable {
