IntelliJ IDEA (Template:IPAc-en<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>) is an integrated development environment (IDE) written in Java for developing computer software written in Java, Kotlin, Groovy, and other JVM-based languages. It is developed by JetBrains (formerly known as IntelliJ) and is available as an Apache 2 Licensed community edition,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and in a proprietary commercial edition. Both can be used for commercial development.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

History

The first version of IntelliJ IDEA was released in January 2001 and was one of the first available Java IDEs with advanced code navigation and code refactoring capabilities integrated.<ref name="JetBrains">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 2009, JetBrains released the source code for IntelliJ IDEA under the open-source Apache License 2.0.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> JetBrains also began distributing a limited version of IntelliJ IDEA consisting of open-source features under the moniker Community Edition. The commercial Ultimate Edition provides additional features and remains available for a fee.

In a 2010 InfoWorld report, IntelliJ received the highest test centre score out of the four top Java programming tools: Eclipse, IntelliJ IDEA, NetBeans and JDeveloper.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In December 2014, Google announced version 1.0 of Android Studio, an open-source IDE for Android apps, based on the open source community edition.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Other development environments based on IntelliJ's framework include AppCode, CLion, DataGrip, GoLand, PhpStorm, PyCharm, Rider, RubyMine, WebStorm, and MPS.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In September 2020, Huawei announced and released version 1.0 of DevEco Studio, an open-source IDE for HarmonyOS apps development, based on Jetbrains IntelliJ IDEA with Huawei's SmartAssist for Windows and macOS.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Features

Coding assistance

The IDE provides certain features<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> like code completion by analysing the context, code navigation which allows jumping to a class or declaration in the code directly, code refactoring, code debugging,<ref>Roman Beskrovnyi, "Debugging in IntelliJ IDEA: a beginner's guide", CodeGym.cc blog, 16 March 2020</ref> linting and options to fix inconsistencies via suggestions.

Built in tools and integration

The IDE provides<ref name=":0" /> integration with build/packaging tools like Maven, Grunt, Gradle, and sbt. It supports databases like Microsoft SQL Server, Oracle, PostgreSQL, SQLite, and MySQL can be accessed directly from the IDE in the Ultimate edition, through an embedded version of DataGrip, another IDE developed by JetBrains.
