The main purpose of java-diff-utils was and is to provide an easy to use toolset to handle diffs of some kind.

This library, at least this fork, does rely on Java 8 and later. Sorry, if you have to stick with older versions.

There are three main entry classes into this library:

• DiffUtils: to calculate patches and deltas
• UnifiedDiffUtils: to process UnifiedDiff files (import / create)
• text/DiffRowGenerator: to provide a difference set in a readable form
• unifieddiff/: contains the new implementation of UnifiedDiff parser tools
  • UnifiedDiffReader.parseUnifiedDiff

To look at the examples, I put it all into the test/examples folder of diffutils.
