引入变量。(Windows下按Ctrl+Alt+V, OSX下按Cmd+Alt+V)

假设调用service。listallpersons()方法 按Ctrl+Alt+V并回车，方法调用的返回值的变量被插入:

List<Person> list = service.listAllPersons();

节省输入，并且不必检查所调用方法的返回类型。在使用泛型时尤其有用，例如:

new ArrayList<String>()

(引入变量)

ArrayList<String> stringArrayList = new ArrayList<String>();

(当然，你可以在按Enter键之前轻松更改变量的名称)

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。

抱歉，如果这已经涵盖了，但简单地有“变化”标签在那里，我可以看到我的本地变化，传入的变化，远程变化只是简单的东西，我不能没有。在Eclipse中，我找不到这样的特性!

另外，像中间点击绑定到“开放声明”这样简单的事情是一个很好的UI添加——我也看不到在Eclipse中实现的东西。

在我工作的地方只有Eclipse，但我正在认真考虑购买个人的Idea许可证....

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)。
