I got how to read using common-csv jar but not how to update a specific field. Can you please give an example ? – Mohit Jain Dec 22 '15 at 05:45
You are not going to be able to update in place (files are stored linearly on disk). But you can read from a file replace the lines or fields you want to change and then write out the new CSV.
