刚接触面向对象，对其非常不了解，接下老师用了一天时间出了一些题让我 们尽量快速进入到面向对象的学习中

/*
 * 根据描述定义出对应的功能类、接口等：
      银行柜台常规的功能有：存款、取款、转账、查询、修改密码等；
     ATM机也具有类似的功能：存款、取款、转账、查询、修改密码等；
     但是银行柜台可以人工操作服务。
     另外不同的银行可以提供一些特殊的便民服务：
         中国银行可以交水、电、气等费用；
        建设银行可以交水、电费，同时还可以交上网费；
        交通银行可以交水费，还可以交交通违章费用；
        工商银行可以交电、气费，还可以交有线电视费；
     另外现在网络也和发达，那么支付宝和微信都可以支持上面的特殊费用的提交。
     那么请大家根据上面的描述来进行设计。
