+## How to Create Comparison Report Java with GroupDocs
+
+In this section we bring everything together to **create comparison report java** end‑to‑end. You’ll see how the pieces we built earlier combine into a single, reusable service that can be called from any part of your application.
+
+### Step‑by‑Step Service Example
+
+1. **Instantiate** `ComparisonService` (your wrapper around `Comparer`).  
+2. **Pass** source and target file paths.  
+3. **Receive** a `Path` to the generated report.  
+4. **Handle** any exceptions gracefully (see the error‑handling pattern later).
+
+> *Pro tip:* Keep the service stateless and thread‑safe so it works well with parallel processing.
