+# Java Installation for Gradle
+
+## Quick Setup
+
+1. **Install Java 21 (recommended for Gradle 8.8):**
+   ```bash
+   sudo apt update && sudo apt install -y openjdk-21-jdk
+   ```
+
+2. **Run the setup script:**
+   ```bash
+   ./setup-java.sh
+   ```
+
+3. **Run Gradle:**
+   ```bash
+   ./gradlew run
+   ```
+
+## Alternative: Java 17
+
+If you prefer Java 17:
+```bash
+sudo apt update && sudo apt install -y openjdk-17-jdk
+./setup-java.sh
+```
+
+## Manual Setup
+
+If you prefer to set JAVA_HOME manually:
+
+```bash
+export JAVA_HOME=/usr/lib/jvm/java-21-openjdk-amd64
+export PATH="$JAVA_HOME/bin:$PATH"
+```
+
+To make it permanent, add to your `~/.bashrc`:
+```bash
+echo 'export JAVA_HOME=/usr/lib/jvm/java-21-openjdk-amd64' >> ~/.bashrc
+echo 'export PATH="$JAVA_HOME/bin:$PATH"' >> ~/.bashrc
+source ~/.bashrc
