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。

IntelliJ具有从代码到jspx文档的智能感知和重构支持。

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!

Idea 8.0有可爱的ctrl+shift+space x 2，可以完成以下自动完成:

 City city = customer.<ctrl-shift-space twice>

解析为

 City city = customer.getAddress().getCity();

通过任何级别的getter /setter。

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。

我经常使用的一件事是设置断点，然后控制它的功能。(在我的上一份工作中，大多数人都使用Eclipse……我记得我很惊讶，没有人能在Eclipse中找到如何做到这一点。)

例如，可以让断点实际上不停止，而只是将消息记录到控制台。这意味着，我不必用“System.out.println(…)”乱写代码，然后重新编译。
