我是学计算机科学与技术专业的大二学生，到了大三就要选修语言课程了，比如vc,java等等，看了j道上的好多文章真是收获不少，尽管很多概念我还不是很明白。
还有两年就毕业了，我想好好学习一下OO方面的东西，所以请banQ前辈推荐一些好书给我等入门者，算是找点“捷径”吧，谢谢

I think the first book is design pattern.
Read that first.
and our company needs some fresh blood but u must be
talented. we can show u the roadmap in j2EE.

Thank you for your advice,sir.
In fact ,I am very interested in computer science and I am glad to spend time in solving a problem such as the aspects of algorithm instead of my intelligence.
I will work hard for my target.

I dont quite understand you.
well, first of all, you have to be clear about which kind of programmer do you wanne be,In application level or in system level?
In application level, properly speaking, the company needs engineer to make a project.
In system level, the company needs more scientists than engineers.
Because most of the products are still in lab and it means th** dont know if it can launch in market or not.
so what technology you need is totally different.
But if you have a sound base in what you learn in school and really understand the linkage between each parts, you can work as any level programmer as you want.
On the contrary, then choose as an application layer programmer is easier.

///////////////////////////////////////////
I will choose the application level.
A sound base I think should contains the subjects such as data structure,algorithm,OS theory,compiler theory and so on,which are more crutial to the one who chooses the system level than the one who chooses the application level.
The Data structure and algorithm are permanent but C++,java are not.
My current goal is to reach the sound base and to study OO thoughts by myself.
I want to hear the opinion from you sir.

Personally, I think you should have more hands-on code
experience.
The basic technology is important but it depends on how much you know about them. I forgot a lot details after graduation. but at least you should know the concept and the big direction in this domain.
now you should read source codes written by the famous programmers.
And from the source codes, you will better understand the theory.
what is the real programming and why OO design pattern is created?
There is a transition in technology evolution. nothing is just a wonder in one second.
Lots of chinese programmers dont even know how to use procedure language. in fact, lots of Gof were using that all the time to simulate OO at that time.
Just right after so many redundant codes need to be written each time, then a new framework is to be created . it is a evolution framework which becomes the OO.
a lot of low level algorithms are still reused today. it is important to know them in concept level at least. if you know the source code, it will be better. I suggest you to read the source code.
The book I suggest you to read:
1. Design Pattern
2. read source code of JBOSS.

###I agree with you.
By reading the classic source codes,I can comprehend the thoughts of software designing well,improve my programming level and know about many kinds of theory well and so on.
I will read the Design Pattern to learn OO thougts.
Is java the precondition of reading the source codes of JBOSS?
I have learned C .Now I am learning C++ using Thinking in C++.

Because all j2ee essence is concentrating on its application server
where you can recognize almost all the frameworks or technology derived from java.
and all the current framework in java are all based on IOC mechanism. so after reading that, you did understand how IOC is realized and how a big application written in java realizes its extensibility and maintainability.
and lots of low level stuff inside web server help you a lot to solidate your knowledge.
what we do in low level till now is still useful in high level.
sometime we need to implement a IOC container ourselves and JBOSS is a good example to dissect.
A good programmer must be able to read the shit code of others.
in the real life, lots of projects are half made. if you need to pick it up, then you must understand it.

From your words I know something that can't learn from books.
The design pattern is about the methods to resolve many special kinds of problems and I can study the knowledge of frameworks by reading the source code of JBOSS.yes
"read the shit code of others."? ^_^,We should read the source codes from the great programmer or good codes such as JBOSS.
"if you need to pick it up, then you must understand it",yes,
The final aim of reading and dissecting the codes with my knowledge is to get the essence of j2ee, then use it well and easily in actual developments.
Now ,It's time for me to take action to work for it.
I am to expect to ask for advice from you sir,Thank you .

下载一个好的J2EE IDE，本人推荐WorkShop Studio
新建一个Hibernate项目，之后找个关系数据库，建立两张表
user
order
order->user_id FK_TO_USER
之后用IDE的数据ORM工具将表变成对象。再搞一个一对多的关系开发。如果你悟性好，就可以马上升仙了。。呵呵
结果是这样的
会变成两个类
user和order
user类有个方法可以得到该用户的所有结果集。只要生成了user这个类就能用这个方法得到对应的订单
public Set getOrders(){
}
order类也有个方法用于得到这张订单的用户类
public user getUser(){
return user;
}
你一步，想一下这样的情况
部门、人员、订单三者
你得到订单这个对象，就能很轻易地用 get_user().get_bm()得到部门。这就是对象编程，这是普通非OOp语言所能做的。。

对java新手来说，要学Design Pattern能不能用Core J2EE Patterns（Best Practices and Design Strategies）这本书？
还有去哪里找source code?
