IDEA所提倡的是智能编码，是减少程序员工作量，那么IDEA具体又有哪些值得推崇呢?25个选择IDEA的理由：

• 智能的选取
  在很多时候我们要选取某个方法，或某个循环或想一步一步从一个变量到整个类慢慢扩充着选取，IDEA就提供这种基于语法的选择，在默认设置中Ctrl+w，可以实现选取范围的不断扩充，这种方式在重构的时候尤其显得方便。

• 丰富的导航模式
  IDEA提供了丰富的导航查看模式，例如ctrl+e显示最近打开过的文件，ctrl+n显示你希望显示的类名查找框(该框同样有智能补充功能，当你输入字母后IDEA将显示所有候选类名)。在最基本的project试图中，你还可以选择多种的试图方式。

• 历史记录功能
  不用通过版本管理服务器，单纯的IDEA就可以查看任何工程中文件的历史记录，但版本恢复时你可以很容易的将其恢复。

• JUnit的完美支持

• 对重构的优越支持
  IDEA是所有IDE中最早支持重构的，其优秀的重构能力一直是其主要卖点之一。

• 编码辅助
  Java规范中提倡的tostring(),hashcode(),equals(),以及所有的get/set方法，你可以不用进行任何的输入就可以实现代码的自动生成，从而把你从无聊的基本方法编码中解放出来。

• 灵活的排版功能
  基本所有的IDE都有重排版功能，但仅有IDEA的是人性的，因为她支持排版模式的定制，你可以根据不同的项目要求采用不同的排版方式。

• XML的完美支持

• 动态语法检测
  任何不符合java规范，自己预定义的规范，累赘都将在页面中加亮显示。

• 代码检查
  对代码进行自动分析，检测不符合规范的，存在风险的代码，并加亮显示。

• 对JSP的完全支持
  不需要任何的插件，完全支持JSP。

• 智能编辑
  代码输入过程中，自动补充方法或类。

• EJB支持
  不需要任何插件完全支持EJB(6.0 支持ejb3.0)

• 列编辑模式
  用过UtralEdit的肯定对其的列编辑模式赞赏不已，因为她减少了很多很多的无聊重复工作，而IDEA完全支持该模式，从而更加提高了编码效率。

• 智能模板
  预 置模板可以让你把经常用到的方法编辑进模板，使用时你只用输入简单的几个字母就可以完成全部代码的编写。例如使用比较高的public static void main(String[] args){}你可以在模板中预设pm为该方法，输入时你只要输入pm再按代码辅助键，IDEA将完成代码的自动输入。

• 完美的自动代码完成
  智能检查类中方法，当发现方法名只有一个时自动完成代码输入，从而减少剩下代码的编写工作。

• Ant 支持
  不需要任何的第三方插件。

• 不使用代码检查
  自动检查代码中不使用的代码，并给出提示，从而使代码更高效。

• 智能代码
  自 动检查代码，发现与预置规范有出入的代码给出提示，若程序员同意修改自动完成修改。例如代码：String str = "Hello Intellij " + "IDEA"; IDEA将给出优化提示，若程序员同意修改IDEA将自动将代码修改为：String str = "Hello Intellij IDEA";

• 正则表达的查找和替换功能
  查找替代支持正则表达，从而提高效率。

• JavaDoc预览支持
  支持JavaDoc的预览功能，在JavaDoc代码中ctrl+q显示JavaDoc的结果，从而提高doc文档的质量。

• 程序员意图支持
  当程序员编码时IDEA时时检测你的意图，或提供建议，或直接帮你完成代码。

• 支持Spy-js（v13.1）
  支持Spy-js,实现代码跟踪。

IDEA are advocating is intelligent coding is to reduce the work of programmers, then IDEA particularly worthy of praise and what it summarized below 25 points, hope to have a more comprehensive description:

• Smart Selection
• In many cases we have to choose a method, or a loop or would like step by step from a variable to the entire class slowly expand the selection, IDEA will offer this choice based grammar, in the default setting Ctrl + w, can be achieved select the range continues to expand, this way at the time of reconstitution is especially convenient.
• Rich navigation mode
• IDEA provides a wealth of navigation viewing modes, such as ctrl + e display recently opened files, ctrl + n show you want to display the class name lookup box (the box also has intelligent supplementary function, when you enter a letter IDEA will show all candidate class name). In the most basic project trying to, you can also choose a variety of ways of trying.
• History function
• Not through the version management server, a simple IDEA can view the history of any work in the file, but when you can easily restore versions of its recovery.


• Perfect support for the JUnit
• Superior support for reconstruction
• IDEA is the oldest of all the IDE support reconstruction, reconstruction of its outstanding ability has been one of its main selling points.
• Coding assistance
• Java specification advocated tostring (), hashcode (), equals (), as well as all get / set methods, you can not make any input you can automatically generate code, which you from the basic method for encoding boring freed.
• Flexible layout features
• Substantially all of the IDE has re-layout features, but only IDEA is human nature, because she supports custom layout mode, you can use different ways depending on the project layout requirements.
• Perfect XML support
• Simple and easy to use GUI interface
• Automatically synchronize with the file system
• When you minimize the IDEA, directly on the file for editing, re-open the IDEA IDEA will automatically complete the update files without re-engineering into the project or refresh.
  • Custom keyboard shortcuts
  • Powerful shortcut set, basically allows the programmer to leave the mouse work.
  • Dynamic Syntax Check
  • Any non-compliance java specification, own predefined specifications burden will be highlighted on the page.
  • Code Check
  • The code is automatically analyzed to detect non-compliant, there is a risk of the code, and highlighted.
  • Full support for JSP
  • Does not require any plug-ins, fully supports JSP.
  • Smart Editor
  • Enter the code process, automatic replenishment method or class.
  • EJB support
  • Does not require any plug-in fully supports EJB (6.0 support ejb3.0)
  • Column editing mode
  • Column editing mode used UtralEdit sure it's admiration, because she reduced a lot of duplication of work boring, and IDEA fully support this mode, thereby further improving the coding efficiency.
  • Smart Templates
  • Preset templates let you edit frequently used method into the template, you only enter when using a few simple letters to complete the preparation of the entire code. For example, using a relatively high public static void main (String [] args) {} You can preset pm for the method in the template, enter the code you simply enter pm press modifier keys, IDEA will be completed automatically entered code.
  • Perfect automatic code completion
  • Intelligent inspection class method, when the discovery method is only one name automatically complete your entry, thereby reducing the remaining code writing work.
  • Ant support
  • It does not require any third-party plug-ins.
  • Do not use the code checks
  • Automatic checking code in the code are not used, and prompt, making the code more efficient.
  • Smart Code
  • Automatically check code and found discrepancies with the preset specification code prompt, if programmers agreed to modify the automatic finish. For example the code: String str = "Hello Intellij" + "IDEA"; IDEA optimization tips will be given, if the programmer agree to amend IDEA will automatically change the code to: String str = "Hello Intellij IDEA";
  • Find and Replace regular expression
  • Find alternative support regular expressions, thereby improving efficiency.
  • JavaDoc preview support
  • Support JavaDoc preview function, ctrl + q to display the results JavaDoc JavaDoc code, thereby improving the quality of doc documents.
  • Programmers intent support
  • When a programmer coding IDEA always detect your intentions, or provide advice or direct help you complete the code.
