+## How to java compare password protected documents
+
+Password‑protected files are common in regulated industries. By passing the password through `LoadOptions`, you keep the comparison flow unchanged while ensuring the library can decrypt the file securely. Remember to never hard‑code passwords; store them in a secure vault or environment variable and inject them at runtime.

+## How to handle large documents java
+
+When documents exceed several hundred megabytes, you may encounter slower processing or higher memory consumption. To mitigate this:
+
+- **Increase JVM heap** (`-Xmx`), especially for batch jobs.  
+- **Enable streaming** where possible – GroupDocs.Comparison processes files in chunks internally, but you can further reduce memory pressure by avoiding loading whole files into memory yourself.  
+- **Run comparisons asynchronously** (see the async example above) to keep your UI responsive.  
+- **Split very large PDFs** into logical sections before comparison if business logic permits.

 ## Integrating with Spring Boot
 
 For developers building microservices, wrap the comparison logic in a Spring service bean:
