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有一个比subversion或Subclipse优秀得多的SVN插件，而且它是有效的!我们在使用Eclipse合并源文件上所浪费的时间是无法想象的。对于IntelliJ，这不是一个问题，因为插件可以帮助你更多。

此外，Subclipse插件也不可靠——我们经常遇到插件认为其他开发人员没有将任何代码签入SVN的情况，但确实存在——CI服务器已经处理了它们!

从Maven POM打开一个项目。 只需选择“打开项目…”导航到你的顶级pom.xml，并按Enter:) NetBeans现在也有这个特性。

我没有用IntellijIdea编写过很多代码，但是在IntellijIdea中，你可以看到括号(if, try/catch, cycle等)之间的代码块在哪里开始，在哪里结束。

在Eclipse中(我在Eclipse 3.2中编码)，您只能手动识别块。

对我来说，它是IDEA的maven支持，特别是在版本9中是首屈一指的。项目与maven模型的动态同步非常棒，使开发变得愉快。

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!
