An open-source Java library for performing diff operations between texts or data: computing diffs, applying patches, generating and parsing unified diffs, and rendering diff output such as side-by-side views. It is a maintained fork of the original Google Code java-diff-utils project, published on Maven Central.

Use cases

• compute the difference between two texts in java
• apply a patch to a file programmatically
• generate unified diff output
• parse unified diff files
• render side-by-side diff view
• show inline word-level diffs with markdown styling
• compare lists of arbitrary objects for changes

When to choose

• you need diff/patch functionality inside a JVM application
• you want to display human-readable diff output like side-by-side or inline diffs
• you need to generate or parse unified diff format

When to avoid

• you need a command-line diff tool rather than a library
• you work outside the JVM ecosystem
• you need binary or image diffing
