在我看来，其中一个优点是依赖结构矩阵: http://www.jetbrains.com/idea/features/dependency_analysis.html#link0

在Lattix的网站上(一个独立的产品)有一个关于DSM使用和好处的很好的介绍: http://www.lattix.com/files/dl/slides/s.php?directory=4tour

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。

IntelliJ有一些相当高级的代码检查(与FindBugs类似但又不同)。

虽然我在使用IntelliJ时非常想念FindBugs插件(Eclipse/FindBugs集成非常酷)。

下面是IntelliJ支持的代码检查的官方列表

编辑:最后，IntelliJ有一个findbugs-plugin。它仍处于测试阶段，但代码检查和FindBugs的组合非常棒!

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。

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。

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)。
