When working with Java applications that need to compare documents, handling RTF files and manually tracking edits between versions can be error‑prone. A smarter approach is to build a programmatic solution that automatically diffs file versions and highlights text changes. In this article, we’ll show you how to compare two RTF files in Java within your cloud‑based apps, using a straightforward workflow powered by the Java REST API.

Steps to Compare RTF Files Using Java

1. Download the GroupDocs.Comparison Cloud Java SDK and create a Java project
2. Obtain and set up your API credentials with the Configuration class
3. Initialize the CompareApi class for comparison
4. Create FileInfo objects for the source and target RTF files
5. Define comparison options with the ComparisonOptions class
6. Load & execute the RTF file comparison request with the comparisons() method

With the outlined steps, developers only require simple API calls to compare RTF documents in Java applications. Instead of creating your own diff engine, you get a production-grade comparison engine with the Cloud REST API. You write minimal Java client logic; the heavy lifting is done by the cloud solution. Developers can decide whether to accept or reject the changes programmatically. Being REST-based, the comparison API does not require heavy dependencies or local libraries for comparing rich text format files.

Code to Compare RTF Files Using Java

The GroupDocs.Comparison Cloud Java SDK helps Java developers compare RTF files with minimal coding effort. It empowers your applications on Windows, Linux, or macOS to spot text changes with just a few API calls. By leveraging the Java REST API, you can seamlessly embed the RTF comparison feature into any Java project. Moreover, the SDK provides a summary of changes in the resulting document, giving you a complete overview of the comparison results and the edits made.
