首先，我喜欢intellij。它至少有100个eclipse所缺乏的特性。在重构、重命名、移动和其他已经提到过的东西时，我所说的可靠性和智能程度是任何夸张都无法形容的。

但是，有一件事intellij不允许，而eclipse做到了。它不允许在同一个vm下同时运行多个项目。

当你有独立的前端、中间、核心、代理项目时…等等，它们都必须相互交互，你不能同时快速修改和调试。我目前处理这个问题的唯一方法是使用ant脚本在依赖的项目中部署和更新jar，或者使用maven。

Eclipse允许在一个ide vm实例下调试多个项目。

Well, for me it's a thousand tiny things. Some of the macros, the GUI layout in general in Eclipse I find awful. I can't open multiple projects in different windows in Eclipse. I can open multiple projects, but then it's view based system swaps a bunch of things around on me when I switch files. IntelliJ's code inspections seem better. Its popup helpers to fix common issues is nice. Lots of simple usability things like the side bar where I can hover over a hot spot and it'll tell me every implementing subclass of a method or the method I'm implementing and from where.

每当我不得不使用Eclipse时，或者看到别人使用Eclipse时，他们似乎可以做我在IntelliJ中可以做的大部分事情，但它花费的时间更长，而且更笨重。

VIM模拟器。这个插件在IDEA中编辑文件时提供了几乎完整的vi/vim/gvim仿真。 支持以下功能: 运动键 删除/修改 插入模式命令 标志着 寄存器 VIM撤销/重做 可视模式命令 一些Ex命令 Some:设置选项 用于搜索和搜索/替换的完整VIM正则表达式 宏 测量 命令行历史记录 搜索历史记录 跳转列表 VIM提供帮助

I can't see ever going back to any other ide because of this plugin.. Best of both worlds... Awesome!. that's what i was lacking in all IDEs.

有很多事情是idea用更简单的方法解决的，或者没有等价的方法:

Autocomplete actions: Doing ctrl+shift+a you can call any idea action from the keyboard without remembering its key combination... Think about gnome-do or launchy in windows, and you've got the idea! Also, this feature supports CamelCasing abbreviations ;) Shelf: Lets you keep easily some pieces of code apart, and then review them through the diff viewer. Local history: It's far better managed, and simpler. SVN annotations and history: simpler to inspect, and also you can easily see the history only for such a part of a whole source file. Autocomplete everywhere, such as the evaluate expression and breakpoint condition windows. Maven integration... much, much simpler, and well integrated. Refactors much closer to the hand, such as loops insertion, wrapping/casting, renaming, and add variables. Find much powerful and well organized. Even in big projects Much stable to work with several branches of a big project at the same time (as a former bugfixer of 1.5Gb by branch sources, and the need to working in them simultaneously, idea shown its rock-solid capabilities) Cleaner and simpler interface... And, simpler to use only with the keyboard, letting apart the need of using the mouse for lots of simple taks, saving you time and giving you more focus on the code... where it matters!

现在，作为开源的…Idea的用户群将呈指数级增长。

如果你把光标放在一个方法上，然后按CTRL+SHIFT+I将弹出方法实现。如果方法是一个接口方法，那么你可以使用上下箭头来循环实现:

Map<String, Integer> m = ...
m.contains|Key("Wibble");

|的位置(例如)您的光标所在的位置。

在IntelliJ中，您可以通过“最后编辑位置”跳过最后编辑位置的历史。Eclipse也有类似的特性，但是Eclipse只返回到编辑位置的一个级别。

拥有历史记录而不仅仅是Eclipse提供的一个级别是一个很好的生产力特性:它充当了一种自动书签的形式，因为您经常希望跳转回您进行更改的地方。我每天都要使用这个功能几次，当我被要求使用Eclipse来做某些事情时，我感到没有这个功能的痛苦。
