IntelliJ IDEA overview
IntelliJ IDEA is an Integrated Development Environment (IDE) for Java and Kotlin designed to maximize developer productivity. It does the routine and repetitive tasks for you by providing clever code completion, static code analysis, and refactorings, and lets you focus on the bright side of software development, making it not only productive but also an enjoyable experience.
Multi-platform
IntelliJ IDEA is a cross-platform IDE that provides consistent experience on Windows, macOS, and Linux.
- For more information about OS-specific instructions, refer to Install IntelliJ IDEA.
- For more information about choosing the right keymap for your operating system, and learning the most useful shortcuts, refer to IntelliJ IDEA keyboard shortcuts.
Supported languages
Development of modern applications involves using multiple languages, tools, frameworks, and technologies. IntelliJ IDEA is designed as an IDE for JVM languages but numerous plugins can extend it to provide a polyglot experience.
JVM languages
Use IntelliJ IDEA to develop applications in the following languages that can be compiled into the JVM bytecode, namely:
Other languages
Plugins bundled with IntelliJ IDEA and available out of the box add support for some of the most popular languages, namely:
- Python (full PyCharm functionality)
- Ruby (full RubyMine functionality)
- PHP (full PhpStorm functionality)
- SQL (full DataGrip functionality)
- Go (full GoLand functionality)
- JavaScript (full WebStorm functionality)
- TypeScript (full WebStorm functionality)
- Thymeleaf
- JSON
- Markdown
- HTML
- XML and XSL
- XPath and XSLT
- Velocity and FreeMarker
- Stylesheets (CSS, Less, Sass)
- Dart
- Erlang
C/C++ are not officially supported in IntelliJ IDEA, but you can use CLion.
You can browse JetBrains Marketplace to find an official plugin that adds support for almost any language, framework or technology used today, or for third-party plugins. For more information about managing plugins, refer to Install plugins.
Do I need a language plugin for IntelliJ IDEA or a separate IDE?
IntelliJ IDEA Ultimate is a superset of most IntelliJ platform-based IDEs. If the bundled language plugins are enabled, it includes support for all technologies that are available within our more specific IDEs, such as PyCharm, WebStorm, PHPStorm, and so on.
So, for example, if your application’s codebase is mainly in Java, but it also uses Python scripts, we recommend using IntelliJ IDEA in combination with the bundled Python plugin. If your codebase is mainly in Python, PyCharm is the right IDE for you.
IntelliJ IDEA editions
IntelliJ IDEA comes in two editions:
- IntelliJ IDEA Ultimate : a full-featured Java and Kotlin IDE. It includes all the features of the Community edition, plus adds support for languages that other IntelliJ platform-based IDEs focus on, as well as support for a variety of server-side and front-end frameworks, application servers, integration with database and profiling tools, and more.
- IntelliJ IDEA Community Edition : a free IDE built on open-source code that provides essential features for Java and Kotlin enthusiasts.
The Early Access program
IntelliJ IDEA Ultimate is available for free within the Early Access Program (EAP). EAP builds are published before the release of a stable product version, and you can download them to try out the new features before they are publicly available in return for your feedback. EAP builds are configured to collect feature usage statistics, and are a valuable source of information for our developers. You can also report an issue if you encounter any problems.
Release Candidate (RC) builds published before a release are also available for download, but require a paid license.
Preview builds published after the release of a stable version that are followed by an official update, also require a paid license and cannot be evaluated for free.
User Interface
IntelliJ IDEA provides an editor-centric environment. It follows your context and brings up the necessary tools automatically to help you minimize the risk of interrupting the developer’s flow.
Take a guided tour around IntelliJ IDEA user interface.
Ergonomic design and customizable appearance
One of the best things about IntelliJ IDEA is its tunability. You can configure virtually anything: the IDE appearance, the layout of tool windows and toolbars, code highlighting, and more. There are also numerous ways you can fine-tune the editor and customize its behavior to speed up navigation and get rid of any extras that distract you from code.
- Configure the colors and fonts for your source code, console output, debugger information, search results, and more. You can choose from a number of predefined color schemes or customize a scheme to create a unique working environment.
- Learn how to configure the editor settings, including appearance, font, code formatting, and more.
- Customize menus and toolbars to spare the annoyance of looking for an action among a dozen buttons you never use.
- Enable the new UI that was designed to reduce visual complexity, provide easy access to essential features, and progressively disclose complex functionality.
Shortcuts for everything
In IntelliJ IDEA, you have shortcuts for nearly every action, including selection and switching between the editor and various tool windows.
Use the most useful shortcuts to invoke frequent actions without switching your focus from the editor and tune your keymap to assign custom shortcuts for your favorite commands.
Watch this video to learn about some of the most useful shortcuts:
Support for Chinese, Japanese, and Korean
You can use IntelliJ IDEA not only in English. By installing a language plugin, you can change the language of the IDE user interface to Chinese, Japanese, or Korean.
To install a language pack plugin, follow the instructions in Install plugins.
Navigation and search
IntelliJ IDEA provides quick navigation not only inside source code files but also throughout the entire project.
One of the most useful shortcuts that is worth remembering is double Shift that brings up the Search Everywhere dialog: start typing and IntelliJ IDEA will look for your search string among all files, classes, and symbols that belong to your project, and even among the IDE actions.
Here are some of the most useful navigation shortcuts:
Go to declaration
For more information about navigating through the source code, refer to Source code navigation, and learn the most useful shortcuts that help you quickly switch between the editor and various tool windows, switch focus, jump to the Navigation bar , and so on.
Recent files and locations
Normally, you work with a small subset of files at a time and need to switch between them quickly. The Recent Files action is a real time-saver here. Press Control+E to see a list of last accessed files. Note that you can also use this action to open any tool window:
Apart from jumping to a recent file, you can also get quick access to Recent Locations — that is code snippets you last viewed or edited. Press Control+Shift+E and you’ll be able to jump to a particular line you modified lately:
File structure
Press Control+F12 to open the file structure popup that gives you an overview of all elements used in the current file and lets you jump to any of them:
Alternatively, use the Structure tool window Alt+7 .
Find action
If you don’t remember the shortcut or the menu path for an action you want to use, press Control+Shift+A and start typing the action name:
Coding assistance
Code completion
IntelliJ IDEA helps you speed up the coding process by providing context-aware code completion.
- Basic completion helps you complete the names of classes, methods, fields, and keywords within the visibility scope:
- Type-Matching completion suggests the most relevant symbols applicable in the current context when IntelliJ IDEA can determine the appropriate type:
For more information about the different types of code completion available in IntelliJ IDEA with examples and productivity tips, refer to Code completion.
Refactorings
IntelliJ IDEA offers a comprehensive set of automated code refactorings that lead to significant productivity gains. For example, when you rename a class, the IDE will update all references to this class throughout your project.
You don’t even need to bother to select anything before you apply a refactoring. IntelliJ IDEA is smart enough to figure out the statement you’re going to refactor. It only asks for confirmation if several choices are possible. Press Control+Alt+Shift+T to open a list of refactorings available in the current context:
For a full list of available refactorings with usage scenarios and the before and after examples, refer to the Refactoring code section.

intellij idea различия community и ultimate версии
Подскажите какие различия и какими средствами Idea реализует отличия версий. Ну например: Поддержа Spring в Ultimate. В community блокируется сборка проектов со Spring, или Idea просто не дает подсказки по Spring? Ну или еще что нить. Так же с hibernate.

Сортировка: Сброс на вариант по умолчанию
Во первых это поддержка плагинов. Много чего не доступно на community. Во вторых Вы верно говорите, работа со Spring невозможна, так как сам проект просто не соберется, подсказки тут не причем. Что касается Hibernate и Jpa, то тут все аналогично, порабоьать с ними не получится. И конечно же нет такой поддержки при работе со сборщиками и git, хотя какие-то базовые вещи доступны. Community версия она скорее для Core, для Enterprise-разработки лучше брать ultimate. Тем более для студентов, преподавателей и некоторых бюджетников она бесплатна.

Я спокойно собирал проект на Spring с community версией. Hibernate и Jpa также работали. Возможно, вы имеете в виду какие-то необязательные подсказки и дополнительные кнопки, которые появляются в Ultimate версии?
12 апр 2020 в 13:16
Ну, например, со Swagger Вы уже не поработаете, отсутствуют так же много фичей по БД. Собрать, в принципе, можно и на community, но насколько это будет удобно при работе с боевыми проектами.
IntelliJ IDEA, Community or Ultimate version? [closed]

Closed 8 years ago .
From the Scala perspective, is there any advantage missed by using the Community version of IDEA over the Ultimate version. I’ve checked the version comparison chart provided and don’t really require many of the features and integrations specified. I’d be interested in things like the mentioned code coverage support, but suspect that it would be Java centric.
Intellij ultimate vs community version for spring framework
as per the Intellij site, the community version does not support the spring and other J2EE frameworks. But I can create a new spring maven project, import in community version IDE and can start development.My question is what are the advantages of ultimate edition and what are the limitations of the community IDE if I start a spring project with it?

There is a trial version of ultimate. Give it a try 🙂 And by no support it means, you won’t get «cool additional» features in community. Things like Spring Dashboard etc.
