How to Install and Use IntelliJ IDEA on Windows 11

IntelliJ IDEA is a powerful and widely used integrated development environment (IDE) designed primarily for Java development, but it also supports Kotlin, Groovy, Scala, and many other programming languages through plugins. Developed by JetBrains, IntelliJ IDEA is known for its intelligent code completion, debugging tools, version control integration, and productivity-focused features.

On Windows 11, IntelliJ IDEA runs smoothly when the required Java Development Kit (JDK) is properly installed. Whether you are a beginner learning Java or a professional developer building enterprise applications, setting up IntelliJ IDEA correctly is essential for an efficient development workflow.

This guide explains how to install and use IntelliJ IDEA on Windows 11, including downloading the IDE, configuring the JDK, and creating your first project.
