我使用intellij而不是eclipse的原因只有一个:可用性

无论是调试、重构、自动完成…Intellij更容易使用一致的键绑定，可用的选项等。在特性方面，intellij很难赶上Eclipse，因为后者比intellij有更多可用的插件，而且很容易扩展。

我不记得在Eclipse中是否可以实现字/行/方法/类换行

在Intellij Idea中，您使用Ctrl+W

IntelliJ具有从代码到jspx文档的智能感知和重构支持。

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。

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。

如果你把光标放在一个方法上，然后按CTRL+SHIFT+I将弹出方法实现。如果方法是一个接口方法，那么你可以使用上下箭头来循环实现:

Map<String, Integer> m = ...
m.contains|Key("Wibble");
