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。

我在IntelliJ中最喜欢的快捷方式是“转到符号”，这在Eclipse中是没有对应的(我发现的)。CTRL-ALT-SHIFT-N让你开始输入和glob类，方法名，变量名等，从整个项目。

数据流分析:如本文所述，过程间的反向流分析和正向流分析。我的经验是基于Community Edition，它在数据流分析方面做得相当好。当代码非常复杂时，它在少数情况下会失败(拒绝做任何事情)。

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。

我使用intellij而不是eclipse的原因只有一个:可用性

无论是调试、重构、自动完成…Intellij更容易使用一致的键绑定，可用的选项等。在特性方面，intellij很难赶上Eclipse，因为后者比intellij有更多可用的插件，而且很容易扩展。

别忘了“和剪贴板比较”。

这是我在IntelliJ中一直使用的，而在Eclipse中没有对应的东西。
