I want to compare two text files and want to highlight the differences. Can any one of you help me in doing that thro Java program.

Thanks in advance.

There are java diff classes scatered all around the internet. i'm sure you could find one by simply typing "java file diff" — Riduidel, Aug 26 '10 at 08:56

Copying one of my answers from a related question:

I would go for netbeans diff api.

Although not a visual implementation, you also have a translation of gnu diff in java.

The google-diff-match-path library seems to provide the functionality you need. Here's a demo of it in action.
