In Java apps for document comparison, processing RTF files, and manually detecting content edits between different versions can be error-prone. A good alternative is to develop a programmatic solution that can automatically perform diff checking across file versions and spot the changes in document text. In this article, we will explore how to compare two RTF files in Java within your cloud-based apps. You can build RTF comparison tools with a straightforward workflow using 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, running on Windows, Linux, or macOS, to detect text changes with just a handful of API requests. Developers can utilize the Java REST API to programmatically implement the RTF comparison feature into their Java applications. You can also get a summary of changes in the resultant document to obtain a comprehensive perspective on the file comparison functionality and the content edits made.
