今天,我们来说说java面向对象最核心的东西,多态.通过多态可以使我们的程序可复用性达到极致,这就是我们为什么要学多态的原因. “多态”(Polymorphic)也叫“动态绑定”(Dynamic Binding)同时也叫“迟绑定”(Late Binding). 动态绑定是指“在执行期间(而非编译期间)判断所引用对象的实际类型,根据其实际类型调用其相应的方法.” 程序代码: public class TestPolymorphic{ public static void main(String a…

我们的身边是不是有这样的一群人,他们心肠不坏,容易感伤,但吐槽似乎是常有的事情,看着时下电视电影,说起哪些哪些自己的泪点.一般都是吃货,别人失眠的时候,TA可能在回忆自己刚做了什么梦.我不是要去评论这样的人,因为我也是那样的人,听歌都能听哭的男生,无所谓好坏,这只是人的一种形态.          我们的身边是不是也有着这样的一些人,他们聪明勤奋,对事物和人有自己独到的见解,做事讲究方法,注重细节,很清楚自己要做什么.可以肯定的是,这样的人一般都比较忙,少有幽默感,一般不会去评论娱乐八卦,音乐艺…

整理着过去的学习笔记,零零碎碎的,偶尔夹杂着当时的心境. 泛泛的学着东西,不很系统,不很深入,倒像是在拾海,有时捡捡贝壳,有时抓抓螃蟹.叹服大海的神奇,还没来得及深钻某个领域. (以下内容写于2016年8月) 敲着简单的C++代码. 有些一眼觉得特简单,不屑一顾, so easy ,早就会了.但是真的去敲时,总会遇见一些预想不到的问题,但也会发现一些小乐趣. 1.“温故而知新” 比如下面这个小练习,第一感觉是7个cout就解决了,然后又想有没有其他办法呢? 2.给自己找乐子 用for循环解决后,…
