    第六周,累得很

     

      开始连轴转,莫名其妙被评为入党积极分子,而实际上我压根没有入党的意愿,天天七八节上党课,睁开眼天亮了,合上眼天黑了,累。

      辅导员让我报名M$创新杯,上网看了下,我现在离这个档次的距离,就跟我要娶徐静蕾当老婆的远大理想一样地遥不可及。现在觉得导员很能装:那天因为要上党课没时间,她说会替我报名;今天因为党课和专业课程冲突的事儿去请假,一见面她就跟演话剧似的跟某某人“隆重介绍”我,可惜这掩饰不了她把这事儿给忘了的实情。我觉得吧,导员把一个学生的这种事儿给忘了太正常、太可以理解了,不过玩这种现场直播就未免太虚伪太雷我了。

      我的神,这文章别让导员看见。

      最近开始真正的尝试去理解面向对象,特别是多态性,貌似目前对C++、Java和Delphi的面向对象机制理解得还算可以,至少摸摸腮帮子就能想起这三位在多态性上的联系和区别;不过还是要说,Delphi真的很精彩。而Ruby这样一门弱类型的动态语言,要谈传统意义上的多态明显不合适;看了些文章,说是Ruby的DuckTyping就是多态的一种体现,不大明白啊,抽空还得琢磨。

      想想现在自己写过的所有程序其实都没有面向对象,只是停留在可以比较熟练地使用各种类库和理解基本的类的继承和overwrite、overload之类,多态涉及很少,更提不到自己去设计这样的类了;现在想想,没有多态的程序设计,只是一种用到了面向对象提供的基本便利性的面向过程的程序设计。一句话,我还嫩得很啊。

      明日班里组织去珠山公园,相当没兴趣,不过也想出去走走……

    呵呵,多态继承这一块 你了解了差不多的时候 看以看看侯捷的 设计模式
    我觉得那样对C++的类的认识和理解 有好处. 那些模式把继承和多态用的真是太爽了

    我再论坛上突然看到你的信息,顺着就看到你的博客了。  大三了啊,一晃真快 我都要毕业了
