IntelliJ调试器有一个非常方便的特性，叫做“表达式计算”，这比eclipses pendant好得多。它有完整的代码完成，我认为它通常“更有用”。

就这篇文章而言，我的时机可能有点不对，但我必须做出回应。

我是一个超级日食迷——从它第一次出现就开始使用它。一个朋友告诉我(10多年前)，这将是一个播放器。他是对的。

然而!我刚刚开始使用IntelliJ，如果您还没有见过或使用过变更列表，那么您就错过了编程的天堂。

The ability to track my changed files (on my development branch ala clearcase) was something I was looking for in a plugin for eclipse. Intellij tracks all of your changes for a single commit, extremely easy. You can isolate changed files with custom lists. I use that for configuration files that must be unique locally, but are constantly flagged when I sync or compare against the repository -- listing them under a changelist, I can monitor them, but neatly tuck them away so I can focus on the real additions I am making.

此外，还有一个提交日志插件，可以输出那些没有与错误跟踪软件集成的SCCS的所有更改的文本。将日志粘贴到票据的工作历史记录中可以捕获文件、它们的版本、日期/时间和分支/标记。太酷了。

我打赌，所有这些都可以通过eclipse中的插件(或未来的增强)来支持;然而，Intellij使这变得轻而易举。

最后，我真的很高兴主流对这款产品的喜爱——按键，所以它很痛苦，但很有趣。

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。

结构搜索和替换。

例如，搜索如下内容:

  System.out.println($string$ + $expr$);

其中$string$是一个文字，$expr$是my.package.and.Class类型的表达式，然后替换为:

  $expr$.inspect($string$);

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。

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。
