俺通过多日的学习,对开发语言有了一定的了解,但是不知道如何从最基础的开始,俺计划一年内掌握一门或者两门编程语言,掌握程度就是能够去软件公司打工。
眼下面对这顿大餐俺不知道从哪里下牙。前两周学过一本VB6,程序都是从课本上抄得,碰到没有答案的题目就不会做了,总之自己不会用所学来的“IF THEN……”用来造句,这更加打击了俺相当程序员的激情和信心。
请大家给俺谈谈经验和学习方法吧,非常感谢!

You Should Study Work Hark, and Write code more! haha !~

先把程序设计的基本东西,语法之类的学一下
然后看看面向对象的书
能够看懂一些简单程序后,建议看看<Java 编程思想>这本书
看书地方法:
1。先看目录,达到能背过地程度,此为统领全书;
2。快速阅读,此时要心静,无杂念,计划2个周看完就2个周,即便第一遍看太懂;
3。看第二遍,一章一章认真阅读,遇有示例,上机实践,直到亲手调试通过为止。此阶段用时大约速读地3倍。
4。探索发现,头脑中勾画些小程序,有空就试验,直到调试通过为止
5。必须有强烈地兴趣爱好
2 数据结构,数据库
3编译原理,操作系统(这两门是理论上的,主要是学习计算机的工作方式)
4 具体各种编程工具。java/ejb/j2ee/j2me或者.net
现在在学C#和ASP.NET共勉共勉
