Java 从基础到进阶学习之路---类编写以及文档凝视.

Java之前在学习过,基础知识还没有忘光,并且这些高级语言实在是太像,所以那些数据类型,或者循环控制流,以及标准设备等等就直接略过不说了.

只是一些重大概念会穿插在文章的介绍中.

So,这些文章适合于那些有一定高级面向对象语言基础的人阅读.

我们首先编写一个学生类.其主要要求要熟悉的内容是:

关于类构造器(构造方法)的认识和理解.

关于方法的编写.

关于成员变量 & this 的使用,

熟悉了这些内容后,我们就能够依照以下的类图编写这个类了.

构造器的參数有姓名,性别,学号.

类图例如以下:

我写的參考的代码例如以下:

我把全部的属性都写成了private类型的,由于这些数据都可写一套set和get方法.....

生成的JavaDoc例如以下.

Next,下一节写一个小游戏,命令行版的无AI的五子棋.

事实上就是对数组和标准输入输出的练习吧.
