☕️ Cursor IDE Configuration for Java Development

This guide shows how to configure Cursor IDE specifically for efficient Java development, leveraging powerful AI assistance, optimal settings, and essential extensions.

---

🧠 1. Enable Cursor AI (LLM Assistant)

Configure AI features via Command Palette (Cmd/Ctrl + K):

> Cursor: Configure LLM Provider

Recommended setup:

• Provider: OpenAI
• Model: GPT-4 or GPT-3.5
• API key: Your OpenAI key

---

📦 2. Recommended Java Extensions

Install Extension Pack for Java:

• vscjava.vscode-java-pack

Included extensions:

• Language Support for Java (redhat.java)
• Debugger for Java (vscjava.vscode-java-debug)
• Java Test Runner (vscjava.vscode-java-test)
• Maven for Java (vscjava.vscode-maven)
• Java Dependency Viewer (vscjava.vscode-java-dependency)
• Visual Studio IntelliCode (VisualStudioExptTeam.vscodeintellicode)

✅ Additional Code Quality Tools (optional):

• Checkstyle for Java (shengchen.vscode-checkstyle)
• SpotBugs (shengchen.vscode-spotbugs)
• EditorConfig (EditorConfig.EditorConfig)

✅ Useful Developer Extensions (optional):

• Docker (ms-azuretools.vscode-docker)
• REST Client (humao.rest-client)
• GitLens (eamodio.gitlens)

🛠️ 3. Configure Java Runtime (JDK)

Set JDK path in settings.json:

{
  "java.home": "/path/to/your/java/home"
}

For SDKMAN-managed JDK:

{
  "java.home": "/home/your-username/.sdkman/candidates/java/current"
}

---

🧪 4. Leveraging Cursor AI in Java Development

• Explain or Refactor code:
  Select code → press Cmd/Ctrl + K → choose action

• Generate new code:
  Write intent in comments → press Cmd/Ctrl + K:

  // Write method to parse JSON into Java object

• Generate Unit tests:
  Select method → Cmd/Ctrl + K → "Write JUnit test for this"

---

🔐 5. Recommended Privacy Settings

Disable telemetry & auto-updates (optional):

{
  "telemetry.telemetryLevel": "off",
  "update.mode": "manual"
}

---

✅ 6. Verify Your Setup

Open your Java project (pom.xml or build.gradle) and test:

• Java Test Runner
• Code navigation and linting
• Cursor AI actions with Cmd/Ctrl + K

---

🎯 Pro Tip:
Make Cmd/Ctrl + K your go-to for AI-assisted development.

✅ Your Cursor IDE Java environment is now optimized and ready!
