Add Java getting started page for Windows dev environment

- Add hub/dev-environment/java.md covering JDK choice, winget install,
  JAVA_HOME configuration, WSL vs native, and recommended editors
- Add Java entry to hub/dev-environment/toc.yml (after Python)
- Add Java card to index.md development paths grid

Note: hub/images/java-logo.png needs to be added for the card icon.

+# Get started with Java on Windows
+
+This guide covers what's different about setting up Java on Windows compared to Mac or Linux, and gets you to a working JDK installation with your environment configured correctly.
+
+## Choose a JDK
+
+Several JDK distributions are available for Windows. Microsoft publishes its own build based on OpenJDK:
+
+- **[Microsoft Build of OpenJDK](https://www.microsoft.com/openjdk)** — free, open source, supported by Microsoft, available for Windows x64 and ARM64
+- **[Eclipse Temurin (Adoptium)](https://adoptium.net/)** — widely used open-source distribution
+- **[Oracle JDK](https://www.oracle.com/java/technologies/downloads/)** — requires a license for commercial use
+
+For most developers, Microsoft Build of OpenJDK or Temurin are good choices.
+
+## Install with winget
+
+Open a PowerShell or Command Prompt terminal and run:
+
+```powershell
+winget install Microsoft.OpenJDK.21
+```
+
+To install Temurin instead:
+
+```powershell
+winget install EclipseAdoptium.Temurin.21.JDK
+```
+
+Verify the installation:
+
+```powershell
+java -version
+```
+
+## Set JAVA_HOME
+
+Unlike on macOS (where `/usr/libexec/java_home` handles this), on Windows you need to set `JAVA_HOME` manually. Many tools — Maven, Gradle, Android Studio — require it.
+
+1. Open **Start**, search for **Environment Variables**, and select **Edit the system environment variables**.
+2. Click **Environment Variables**.
+3. Under **System variables**, click **New** and set:
+   - Variable name: `JAVA_HOME`
+   - Variable value: the path to your JDK, for example `C:\Program Files\Microsoft\jdk-21.0.x.x-hotspot`
+4. Find the **Path** variable under System variables, click **Edit**, and add `%JAVA_HOME%\bin`.
+5. Click OK to close all dialogs, then open a new terminal and verify:
+
+```powershell
+echo $env:JAVA_HOME
+java -version
+javac -version
+```
+
+> [!TIP]
+> If you have multiple JDKs installed, the one listed first in `Path` takes precedence. Tools like [SDKMAN](https://sdkman.io/) (via WSL) or [jEnv](https://www.jenv.be/) can help manage multiple versions.
+
+## WSL or native Windows?
+
+For most Java development — web backends, Android, enterprise apps — native Windows works well. Use WSL if your build tooling or deployment target is Linux-specific, or if you're working in a team where everyone else is on Linux/Mac and you want environment parity.
+
+## Recommended editors
+
+- **[Visual Studio Code](https://code.visualstudio.com/)** with the [Extension Pack for Java](https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack) — lightweight, works well for most projects
+- **[IntelliJ IDEA](https://www.jetbrains.com/idea/)** — full-featured IDE, the Community edition is free
