CJSDN版主HenryShanley写道：

I am very glad to see that you have written 9 articles about various areas in Java. And constantly share your articles free with others. You really deserve to have some points here, Thanks you 臧圩人.

Couple of points related to this article:
- I think English terminologies are also important in the interviews.
e.g. Interviews should also know that 继承、多态、重载和重写 are "Inheritance, Polymorphism , overloading and overwriting" in English respectively. So maybe we could add them besides their Chinese names.
(I remember I used to read a book from "张洪斌", although maybe his book is the best, he explains theories in a very very understandable term. And he also dislikes the awkward Chinese translation to some computer terminologies)

>我们可以把JAVA中的类分为以下三种：
- Don't forget about the inner class.

> 3. 接口类：使用interface定义的类。
- Interface(s) are called interface(s). They should not be referred to as "Interface classes". It is confusing.

- This theory could be demonstrated very easily using images. e.g. Class diagrams would be a good option.

请问是否对 native 方法了解呀！

能否抽出一节来聊下 java native 方法

为啥面试喜欢面试这个呢？？有什么用？我感觉谁写程序的时候一般不会考虑这个吧！

34 楼 soartju 2008-08-01  

支持下

33 楼 yuankai 2008-08-01  

一直在关注LZ的博客，很期待LZ的多线程，虽然在项目中用的地方不多，但是做为一名java开发人员还是必须懂。建议LZ的文章中能增加UML图效果将会更好（特别是多线程）。谢谢！

楼主如有点教学经验，而且J2EE也牛的话建议楼主开个JAVA培训办，绝对能带出些高徒来啊

强烈支持,这期难度稍小,呵~~

25 楼 constant 2008-07-31  

不错，每期都看！mark

24 楼 gotothework 2008-07-31  

是不是少了一种类？在JDK1.5之后又新增加了枚举类

23 楼 iceim 2008-07-31  

关注LZ的文章！

22 楼 yujiang 2008-07-31  

JDK1.5+ 可以的 称为 返回值协变

21 楼 kakaluyi 2008-07-31  

重写后的返回值可以改变吗

20 楼 MarkDong 2008-07-31  

普通类，这个名字有点儿普通，呵呵。
英文中讲这一种类称为concrete class，好像一般翻译为具体类或直接翻译成类。

19 楼 senlinxue1982 2008-07-31  

最难的还是javaSE核心技术啊~一定要有时间就多来学习！
