Not the source code but steps you can follow:

1. display data in textboxes.
2. make an update button.

3. onclick of update button do following:

   3.1 get values from textboxes.

   3.2 connect to database.

   3.3 create an update query and run that query.

This tutorial should get you started. It uses EclipseLink to access the database.
