How to install IntelliJ IDEA 2021 on Windows OS:

In this tutorial, you’ll learn how to download and install IntelliJ IDEA 2021 Software on a windows 8/10 PC.


IntelliJ IDEA is a cross platform integrated development environment (IDE) developed by JetBrains and it’s written in Java and Kotlin for developing desktop and mobile application software. The IDE comes in two versions, ie a community edition and a proprietary Ultimate edition.

Android Studio, an open source IDE for Android apps is based on the open source community edition of IntelliJ IDEA and other development environments based on IntelliJ’s framework include; PyCharm, Rider, RubyMine, AppCode, CLion, etc…



Some of the features that sets IntelliJ IDEA apart include the following;

  1. Plugin Ecosystem:

Both versions of the IDE support over 3000 plugins each through which one can add additional functionality to the IDE and these can be downloaded and installed either from IntelliJ’s plugin repository website or through the IDE’s inbuilt plugin search and install feature.

  1. Supports a large number of languages:

Both versions of the IDE (ie community and ultimate editions) support quite a good number of differing languages with some via plugins.

  1. Coding assistance:

The IDE provides features like code completion by analyzing the context, code navigation which allows jumping to a class or declaration in the code directly, code refactoring, code debugging and options to fix inconsistencies via suggestions.

  1. Built-in tools and integration:

The IDE provides integration with build/packaging tools like grunt, bower, gradle and SBT. 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.

  1. Supports a large number of technologies and frameworks:

The IDE also supports a large number of differing frameworks for both versions such as Django, Tomcat, weblogic, Node.js, etc for only the Ultimate edition and  Maven, JavaFX, Junit, etc for both Community and Ultimate Edition.
