The premier intelligent IDE for Java, Kotlin, and polyglot enterprise development.
IntelliJ IDEA remains the industry benchmark for Integrated Development Environments (IDEs) in 2026, specifically optimized for JVM-based ecosystems and modern full-stack engineering. Developed by JetBrains, its technical architecture leverages a deep-indexing engine that creates a comprehensive semantic model of the codebase, enabling unparalleled refactoring capabilities, context-aware code completion, and proactive error detection. As of 2026, the tool has fully integrated 'AI Assistant,' a LLM-powered module that doesn't just autocomplete code but understands architectural patterns, assists in migration of legacy monoliths to microservices, and generates unit tests based on runtime behavior. The IDE supports a wide array of languages beyond Java, including Kotlin, Scala, Groovy, and through the Ultimate edition, comprehensive frameworks for web development like React, Angular, and Spring. Its market position is solidified by its 'Developer Experience' (DevEx) focus, offering a unified workflow that includes integrated database management, terminal, version control systems, and container orchestration. For enterprise architects, IntelliJ IDEA serves as the primary gateway for remote development via JetBrains Gateway, allowing high-performance coding on thin clients while the compute-intensive indexing occurs on powerful remote servers or cloud dev-environments.

Explore all tools that specialize in ai-assisted coding. This domain focus ensures IntelliJ IDEA delivers optimized results for this specific requirement.
Context-aware completion that suggests only types/methods compatible with the current cursor position based on semantic analysis.
Global code transformations (Rename, Extract Method, Inline) that maintain reference integrity across the entire project.
CPU and Memory profiling using JFR (Java Flight Recorder) and Async-profiler directly within the IDE.
Thin-client protocol for connecting to remote backends (SSH, WSL, Docker, or JetBrains Space).
A full-featured database IDE embedded within IntelliJ for SQL editing, schema navigation, and data export.
Search for code patterns based on syntax tree structures rather than just text strings.
Built-in decompiler that allows developers to step into third-party library code even without source JARs.
Download and install JetBrains Toolbox for version management.
Launch IntelliJ IDEA and select the UI theme (New UI or Classic).
Configure SDKs by downloading or pointing to a local JDK (Amazon Corretto, OpenJDK, etc.).
Import project via VCS (Git) or by opening a local directory containing a pom.xml or build.gradle.
Wait for the initial indexing process to complete for full semantic analysis.
Install 'AI Assistant' plugin from the Marketplace for generative coding capabilities.
Configure 'Project Structure' to define modules, libraries, and facets.
Set up 'Run/Debug Configurations' for local application execution.
Connect to external databases using the integrated 'Database' tool window.
Enable 'Checkstyle' or 'SonarLint' plugins to enforce enterprise coding standards.
