数据结构我知识浅显的学了一部分.数学也是..目前在一家公司做JSP..
请各位大大说说我以后怎样深入比较合适.
不胜感激.
谢谢.

我觉得呢 脑子够使 什么都好说 哈哈
理解数据结构当然好了，我也只是知道一点点，
想真正学好JAVA, 知道什么才是最最重要的，最最需要掌握的吗？ API 啊
这是前人们的心得体会啊

复杂的数据结构很少用得上，真正用到的可能是参加比赛吧
数学好像也没多用，不过在“图”方面有用

从我个人的,到目前的经验来看
好想不是很需要数学的东西
当然,你知道的越多越好了
知识没有害处

It depends what job you get. I'm really good at math, data structure, and algorithm, and had been hired as an expert on algorithm to solve major networking problems in telecom industry. I got a super-programmer reputation in that once world famous company.

However, believe me or not, I almost got fired because my math was not good enough for another company. Sad

Thanks God! I was lucky enough, and had been moved to another group in the same company, the manager was willing to use my different expertise...Smile

那你可是太牛了
我数学比较弱
好在现在的工作不是很需要数学
不知道以后会不会需要

对了你开发什么算法要用到那么高深的数学知识呢?
都是数学的什么内容?

Graph theory (for networking), statistics (for forecasting), operation research (for optimization, etc), ...

There are a lot more, but I don't know them. Sad

I think google is using fuzzy logic in their search engine, of course, in addition to a lot more math there already for sure.

Google was started on real good distribute computing by using a lot of cheep and other people thrown-away computers. Smile

Cooperative and efficient use of thousands of cheap computers are not easy for sure...

I remember I found google search engine on early 2000, the search speed comparison to other search engines was lightening to slow-old-cow. Hehe... searching the same thing is reduced from several minutes or even not found to 0.03 seconds. Wow!!!!!!!!!!!!!!!!!!!!!!!!!!

One of my coworkers just quited his job to enter aeronautics industry to do math oriented computing, Operation Research (OR) !!!

Envying him ...

版主太牛，我个人认为，要深入学习编程和参加高层次的程序开发的话，高数是必不可少的····但是学好数学真的容易吗？？？不容易呀，怎么办····只好无奈

Actually, more important: discrete math

离散数学
太难了
看着封面就头疼

Why? Sit down, and read 1-2 chapters first.

I don't know why. Discrete math is easy to me, I never took the course, skipped by talking around the adviser, but I taught the course, private tutored several students... hehe Smile

我只会几何
初中到高中
基本上几何都是满分
还有物理的电学
哈哈
其他就不行了
以后就方仲永了
什么也不行了
哈哈

"什么也不行了", became "元老"
"以后就方仲永了", we need to learn from "方仲永"了 Smile.

Actually, I did not know who was"方仲永", did a google search. Wow, many many came out. Here is a good link "方仲永" related, just in case someone else is just as ignorant as I was:
