我在IntelliJ中一直使用的东西是在我输入时重构。我用两种ide重写了打印输出的类(最初是在eclipse中编写的)，用IntelliJ编写相同的类比用eclipse少了大约40%的按键/鼠标点击。

除非Eclipse对不完整的代码段支持同样多的重构，否则我不会使用它。

以下是IntelliJ 8.0/8.1的特性列表[http://www.jetbrains.com/idea/features/index.html]

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。

显示导航栏ALT-Home。

我最近发现IntelliJ IDEA与Eclipse相比至少有两个优点。

如果试图在JSP代码编辑器中使用代码格式化，JSP脚本就会出错。Eclipse变得有点疯狂，它到处发布随机的代码片段。IDEA表现得很好。

另一件事是在JBoss服务器上部署应用程序的速度。IntelliJ正在替换JBoss tmp文件夹中的应用程序，因此重新部署非常快。Eclipse WTP正在替换deploy文件夹中的应用程序，而后者的持续时间要长得多。

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。

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。
