An Integrated Development Environment (IDE) combines a code editor, compiler integration, debugger, and project management in one application. For Java, a good IDE dramatically speeds up refactoring, navigation, and testing.

Choosing an IDE

IDE Best For Cost
IntelliJ IDEA Professional development, Spring Community free / Ultimate paid
Eclipse Enterprise, plugin ecosystem Free
VS Code Lightweight editing, polyglot projects Free
NetBeans Beginners, Maven/Gradle projects Free
BlueJ Teaching and learning Java Free

Most professional teams use IntelliJ IDEA or Eclipse. Beginners often start with IntelliJ Community or VS Code.

IntelliJ IDEA

JetBrains’ flagship Java IDE offers the best overall coding experience: smart code completion, inline refactoring, integrated test runners, and first-class Spring Boot support.

  • Website: jetbrains.com/idea
  • Editions: Community (free) covers Java, Kotlin, and Android basics; Ultimate adds Spring, Jakarta EE, and database tools.

Setup steps:

  1. Download and install IntelliJ IDEA.
  2. Open New Project → Java and select your installed JDK.
  3. Install plugins as needed: Lombok, Checkstyle-IDEA, SonarLint.

Useful shortcuts:

Action Windows/Linux macOS
Find class Ctrl+N Cmd+O
Refactor rename Shift+F6 Shift+F6
Run tests Ctrl+Shift+F10 Ctrl+Shift+R
Quick fix Alt+Enter Option+Enter

Eclipse

Eclipse is a mature, extensible open-source IDE widely used in enterprise and academic settings. The Eclipse IDE for Java Developers package includes Maven integration and Git support.

  • Website: eclipse.org
  • Spring Tools: Install Spring Tools 4 from the Eclipse Marketplace for Spring Boot development.

Setup steps:

  1. Download “Eclipse IDE for Java Developers.”
  2. Select a workspace directory on first launch.
  3. File → New → Java Project, set JDK, create a main class.

Eclipse uses a workspace/project model. Import existing Maven or Gradle projects via File → Import.

Visual Studio Code

VS Code is a lightweight editor, not a full IDE, but the Extension Pack for Java (by Microsoft/Red Hat) adds debugging, Maven/Gradle support, and test discovery.

Setup steps:

  1. Install VS Code.
  2. Open Extensions (Ctrl+Shift+X), search “Extension Pack for Java”, install.
  3. Open a folder containing a Maven pom.xml or Gradle build.gradle.
  4. VS Code detects the project and prompts for JDK selection.

VS Code works well when you work across Java, JavaScript, and DevOps configs in one repo.

NetBeans

Apache NetBeans provides a straightforward UI with built-in Maven and Ant support. It is a solid choice for learners and teams that prefer a batteries-included free IDE.

Create a new Maven Java project: File → New Project → Maven → Java Application.

BlueJ

BlueJ is designed specifically for teaching object-oriented programming. Its visual class diagram and interactive object inspection help beginners understand how classes and objects relate.

BlueJ is ideal for classroom use but lacks the advanced refactoring and framework tooling of IntelliJ or Eclipse.

Oracle JDeveloper

JDeveloper is Oracle’s IDE tailored for Oracle Database, ADF, and Java EE applications. It is primarily used in Oracle-centric enterprise environments.

Recommended VS Code / IntelliJ Settings for Java 

  # .editorconfig (works across IDEs)
root = true

[*.java]
indent_style = space
indent_size = 4
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

Enable format on save in your IDE to keep code style consistent. Use the project’s Maven/Gradle formatter plugin if the team shares a style definition.

Next Steps

After choosing an IDE, proceed to Installing Java if you have not set up the JDK, then write your first program in Hello World.
