Java是一个通用的编程语言,其实可以干很多事,怎么学Java就看怎么用了. 但有一些一般的步骤: 1.熟悉一种文本编辑器,比如Vim, Emacs, Notepad++, TextMate等.知道哪些是开源的,哪些是闭源的,哪些要收费.养成不用盗版软件的习惯.2. 安装JDK(建议用你的Linux发行版自带的软件包管理器安装openjdk,过程中可能需要读发行版特定的文档)3. 写一个Java的Hello world程序,并用命令行工具javac编译,再用java命令运行这个程序.过程中熟悉源

一年前由于工作需要从微软技术栈入坑Java,并陆陆续续做了一个Java后台项目,目前在搞Scala+Java混合的后台开发,一直觉得并发编程是所有后台工程师的基本功,所以也学习了小一年Java的并发工具,对整体的并发理解乃至分布式都有一定的提高,所以想和大家分享一下. 我的学习路线 首先说说学习路线,我一开始是直接上手JCIP(Java Concurrency in Practice),发现不是很好懂,把握不了那本书的主线,所以思索着从国内的作者开始先,所以便读了下方腾飞的<Java并发编程的艺

Java泛型简明教程 博客分类: Java综合 JavaApple数据结构CC++ Java泛型简明教程 本文是从 Java Generics Quick Tutorial 这篇文章翻译而来. 泛型是Java SE 5.0中引入的一项特征,自从这项语言特征出现多年来,我相信,几乎所有的Java程序员不仅听说过,而且使用过它.关于Java泛型的教程,免费的,不免费的,有很多.我遇到的最好的教材有: The Java Tutorial Java Generics and Collections ,
