Technical Specifications & System Requirements
Software notes
Features
- Whole-project indexing powers exceptionally accurate code completion, navigation, and inspections for Java and Kotlin, catching type errors, unused code, and likely bugs as you type rather than at compile time.
- Refactorings such as rename, extract method, inline, and change signature update every genuine reference across the project safely, which makes restructuring large, unfamiliar codebases far less risky than find-and-replace editing.
- The unified installer ends the Community-versus-Ultimate download confusion: the core IDE is free forever in the same program, and Pro features arrive as a trial you can evaluate and then keep or let lapse.
- Maven and Gradle projects open with almost no configuration, and the built-in debugger, test runner, Git client, and terminal cover the full daily workflow without assembling a stack of separate tools and extensions.
- JetBrains updates IDEA on a predictable cycle with strong support for the newest Java releases, Kotlin K2 mode, and current Spring versions, so the IDE rarely lags behind the platform it targets.
Considerations
- IntelliJ IDEA is heavy software: the download is roughly 1.2 GB, it recommends 8 GB or more of system RAM, and large projects can feel sluggish on older laptops while indexing is running.
- The Pro feature set - including the deepest Spring support, database tools, and the profiler - requires a paid JetBrains subscription once the included trial period ends, even though the core remains free.
- The sheer density of menus, settings, and tool windows can overwhelm beginners, who often need a guided tour or a course before the interface stops feeling like an aircraft cockpit.
About & Overview: IntelliJ IDEA Community for Windows PC
IntelliJ IDEA is JetBrains' flagship integrated development environment for Java and Kotlin, built around a deep understanding of your whole project rather than individual files. It indexes every class, method, and dependency so its code completion, inspections, and refactorings are context-aware: rename a method and every call site updates safely, extract a variable and the IDE picks a sensible name and type, and hundreds of inspections flag bugs, dead code, and clumsy constructs as you type. Version 2026.2.3 is distributed the new way: since the 2025.3 generation JetBrains ships one unified installer instead of separate Community and Ultimate downloads. The core feature set - Java and Kotlin editing, debugging, Git integration, Maven and Gradle support, JUnit testing - is free forever, and the same installer also includes the Pro feature set (advanced Spring and Jakarta EE support, database tools, profiler, HTTP client and more) as a trial you can later keep by subscribing or drop by simply continuing on the free core. The IDE bundles its own JetBrains Runtime, so no separate Java install is needed to launch it, although you still add a JDK such as Temurin as the project SDK. It is best for Java and Kotlin developers of every level, Android developers working in the platform Android Studio is based on, and students who want the IDE their course or employer most likely uses. A real scenario: a developer opens a large Spring Boot codebase cloned from work, IDEA indexes it once, and within minutes they can navigate from a REST controller straight into the service and repository layers, run the test suite from the gutter icons, and refactor a shared DTO without fear of breaking forty call sites.
How to Install & Verify IntelliJ IDEA Community for Windows PC
Get idea-2026.2.3.exe from JetBrains. There is no longer a separate Community download - this single installer contains the free core plus the Pro trial.
Launch the EXE, choose the install folder, and optionally tick the desktop shortcut, PATH, and file-association options for .java and .kt files.
On first launch, import settings if offered, pick a theme, and either start the included Pro trial or continue directly with the free core features - no licence key is needed for the core.
The IDE runs on its bundled JetBrains Runtime, but your projects need their own JDK. Download one such as Temurin 25 from the New Project screen or add an existing installation under Project Structure.
Open a Maven or Gradle project folder and let the initial indexing finish; completion, navigation, and inspections become fully accurate once indexing completes.

Frequently Asked Questions & Verification Guide
Is IntelliJ IDEA free to use?
Yes, for its core feature set. Since 2025.3 JetBrains ships one unified IntelliJ IDEA: Java and Kotlin development, debugging, Git, Maven and Gradle support are free forever, including for commercial projects. The same installer includes Pro features such as advanced Spring tooling and database tools as a trial; after the trial you can subscribe or simply keep using the free core, and the IDE does not lock you out.
Is there still a separate IntelliJ IDEA Community Edition download?
No. JetBrains replaced the separate Community and Ultimate installers with a single unified distribution starting with the 2025.3 generation, and 2026.2.3 follows that model. Downloading 'IntelliJ IDEA' from jetbrains.com gives you the free core (the successor to Community) plus a Pro trial in one installer - if a site offers you a separate old Community EXE, it is an outdated build.
Is IntelliJ better for beginners?
It depends on what you are learning. For Java or Kotlin, beginners benefit from IDEA's inspections, which explain mistakes in plain language and offer one-click fixes, effectively tutoring as you code. The trade-off is a dense interface with many panels, so absolute beginners may prefer to follow a short setup tutorial rather than exploring unaided.
Does IntelliJ support Python or JavaScript?
Full Python development belongs to PyCharm, JetBrains' Python IDE, although Python files can be opened and basic editing is possible with plugins in the Pro edition. JavaScript and TypeScript support is a Pro feature in IDEA. If Python or web front-end work is your main job, JetBrains intends you to use PyCharm or WebStorm instead.
Do I need to install Java before installing IntelliJ IDEA?
No. IntelliJ IDEA bundles the JetBrains Runtime it needs to run itself. You do still need a JDK - for example Temurin 25 - configured as your project's SDK so your own code can compile and run, and the IDE can download one for you from the project setup screens.
