通过视频学习比传统的大课堂学习更适合成人化的学习规律。有人说大课堂气氛好，学习氛围浓，热闹，可以认识很多人。 是一种简化的C++语言 是一种安全的语言，具有阻绝计算机病毒传输的功能 http://www.jdon.com/去下载，或到同济技术论坛的服务器ftp://nro.shtdu.edu.cn去下，安装上有什么问题，可以到论坛上去提问。 你现在最缺的是实际的工作经验，而不是书本上那些凭空想出来的程序。 你现在最缺的是实际的工作经验，而不是书本上那些凭空想出来的程序。 我大二，Java也只学了一年，觉得还是看thinking in java好，有能力的话看英文原版(中文版翻的不怎么好)，还能提高英文文档阅读能力。 自从Sun推出Java以来，就力图使之无所不包，所以Java发展到现在，按应用来分主要分为三大块：J2SE,J2ME和J2EE,这也就是Sun ONE(Open Net Environment)体系。J2SE就是Java2的标准版，主要用于桌面应用软件的编程；J2ME主要应用于嵌入是系统开发，如手机和PDA的编程；J2EE是Java2的企业版，主要用于分布式的网络程序的开发，如电子商务网站和ERP系统。 如果要向java web方向发展也要吧看看《Java web从入门到精通》学完再到《Struts2.0入门到精通》这样你差不多就把代码给学完了。有兴趣可以看一些设计模块和框架的包等等。 自从Sun推出Java以来，就力图使之无所不包，所以Java发展到现在，按应用来分主要分为三大块：J2SE,J2ME和J2EE,这也就是Sun ONE(Open Net Environment)体系。J2SE就是Java2的标准版，主要用于桌面应用软件的编程；J2ME主要应用于嵌入是系统开发，如手机和PDA的编程；J2EE是Java2的企业版，主要用于分布式的网络程序的开发，如电子商务网站和ERP系统。 Sun公司看见Oak在互联网上应用的前景，于是改造了Oak，于1995年5月以Java的名称正式发布。Java伴随着互联网的迅猛发展而发展，逐渐成为重要的网络编程语言。 你一定会高兴地说，哈哈，原来成为Java高手就这么简单啊!记得Tomjava也曾碰到过一个项目经理，号称Java很简单，只要三个月就可以学会。 Java 编程语言的风格十分接近C、C++语言。 有时间再研究一下MVC结构（把Model-View-Control分离开的设计思想） 一直感觉JAVA很大，很杂，找不到学习方向，前两天在网上找到了这篇文章，感觉不错，给没有方向的我指了一个方向，先不管对不对，做下来再说。 http://www.jdon.com/去下载，或到同济技术论坛的服务器ftp://nro.shtdu.edu.cn去下，安装上有什么问题，可以到论坛上去提问。 Jive的资料在很多网站上都有，大家可以找来研究一下。相信你读完代码后，会有脱胎换骨的感觉。遗憾的是Jive从2.5以后就不再无条件的开放源代码，同时有licence限制。不过幸好还有中国一流的Java程序员关注它，外国人不开源了，中国人就不能开源吗？这里向大家推荐一个汉化的Jive版本—J道。Jive(J道版)是由中国Java界大名 鼎鼎的banq在Jive 2.1版本基础上改编而成, 全中文，增加了一些实用功能，如贴图，用户头像和用户资料查询等，而且有一个开发团队在不断升级。你可以访问banq的网站 关于设计模式的资料，还是向大家推荐banq的网站 http://www.jdon.com/，他把GOF的23种模式以通俗易懂的方式诠释出来，纯Java描述，真是经典中的经典。 任职于太阳微系统的詹姆斯·高斯林等人于1990年代初开发Java语言的雏形，最初被命名为Oak，目标设置在家用电器等小型系统的程序语言 如果要向java web方向发展也要吧看看《Java web从入门到精通》学完再到《Struts2.0入门到精通》这样你差不多就把代码给学完了。有兴趣可以看一些设计模块和框架的包等等。
