If I were describing a practical Java setup in 2026, it would look something like this:
- IDE: IntelliJ IDEA (Ultimate if available, Community for many projects)
- Lightweight editing: VS Code
- Build: Maven or Gradle (Gradle is increasingly common for larger projects)
- JDK: Temurin/OpenJDK 21 or newer LTS depending on the project
- Testing: JUnit 5 + Mockito
- Formatting: Spotless + google-java-format or the IntelliJ formatter
- Static analysis: Error Prone, SpotBugs, Checkstyle (depending on the codebase)
- Containers: Docker + Testcontainers
- Version control: Git with GitHub or GitLab
IntelliJ is still the strongest overall
For professional Java development, IntelliJ remains the benchmark because of its:
- excellent refactoring support
- deep understanding of generics and type hierarchies
- reliable debugging
- Spring Boot support
- JPA/Hibernate tooling
- Maven/Gradle integration
- profiler and database tools (Ultimate)
On large enterprise projects (Spring Boot, Micronaut, Quarkus, Jakarta EE), it's still the IDE many teams standardize on.
VS Code has become genuinely capable
VS Code isn't just a text editor with Java extensions anymore. With the Java extension pack, it offers:
- semantic code completion
- refactoring
- debugger
- Maven and Gradle support
- JUnit test explorer
- Spring tooling
- Git integration
It's a solid choice if you:
- work across many languages (Java, TypeScript, Go, Python, Rust)
- prefer a lighter editor
- spend a lot of time in terminals and containers
- don't need every advanced Java inspection
Where IntelliJ still pulls ahead
On very large codebases (millions of lines), IntelliJ generally provides:
- more accurate code analysis
- faster navigation between symbols
- stronger refactoring confidence
- better inspections
- richer framework-specific support
These differences become more noticeable as project complexity increases.
Where VS Code shines
If your workflow is:
- Java backend
- React frontend
- Docker
- Kubernetes
- Terraform
- GitHub Actions
then VS Code provides a very unified experience because you're using one editor across everything.
My recommendation by use case
- Enterprise Java / Spring Boot: IntelliJ
- Learning Java: Either works well
- Polyglot developer: VS Code is very compelling
- Large monorepos: IntelliJ usually has the edge
- Occasional Java work: VS Code is often sufficient
Overall, I'd say the landscape in 2026 is that IntelliJ is still the "best Java IDE" for developers who spend most of their time in Java, while VS Code has matured into a credible option that many professionals use successfully—especially those who value a single, lightweight editor for multiple languages rather than maximizing Java-specific features.
