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。

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。

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($string$);

Alt+Insert以列模式编辑文本。

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。

Idea 8.0有可爱的ctrl+shift+space x 2，可以完成以下自动完成:

 City city = customer.<ctrl-shift-space twice>

解析为

 City city = customer.getAddress().getCity();

通过任何级别的getter /setter。
