Well, for me it's a thousand tiny things. Some of the macros, the GUI layout in general in Eclipse I find awful. I can't open multiple projects in different windows in Eclipse. I can open multiple projects, but then it's view based system swaps a bunch of things around on me when I switch files. IntelliJ's code inspections seem better. Its popup helpers to fix common issues is nice. Lots of simple usability things like the side bar where I can hover over a hot spot and it'll tell me every implementing subclass of a method or the method I'm implementing and from where.

每当我不得不使用Eclipse时，或者看到别人使用Eclipse时，他们似乎可以做我在IntelliJ中可以做的大部分事情，但它花费的时间更长，而且更笨重。

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。

我认为您可以坚持使用这两个ide中的任何一个。 不要“担心在您没有使用的IDE中错过一个巨大的好处”的最好迹象是我们在Eclipse爱好者和IntelliJ爱好者之间看到的很长的争论。这是一个很好的迹象，双方拥有几乎相同的力量，这使得这场长期的讨论得以幸存。

有一件事IntelliJ做得比Eclipse好得多，那就是清空你的口袋!

然而，我确实更喜欢使用它，它比Eclipse有一个很大的优势，就是它与文件系统同步的方式，对于大项目和慢速的计算机(是的，在工作环境中，PC的速度比我们家里的慢得多)，Eclipse似乎与IntelliJ相比似乎更快，尽管初始索引时间较慢。

IntelliJ社区版显然可以免费使用它，但你很快就会想要那些额外的重构和CC版不包含的小东西。

在我看来，这通常是一个更好的用户体验，但是否值得这个成本是每个开发者自己要回答的问题。

但是让我们感激我们现在有三个很棒的Java ide, NetBeans一直在变得更好。

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。
