Write CSV processing script in Java

I have an existing R script that's about 30 lines of code that I want rewritten into a simple Java app.

It reads an unknown csv file, detects the fields and outputs a text summary including: Common Value Counts (with Other and NA/Blank) and Min-Max Summary (uses string length for text fields). Summary data should be saved to a database.

My existing Java app schedules file downloads. I want to add a new tab to an existing Java app to track results in a grid. I also want a new checkbox so user can control whether to run the file summary or not.

Data Output Sample:


1,21,Address,1,800 BOYLSTON ST,3257

2,21,Address,1,200 FANEUIL HALL MARKET PL,2584

3,21,Address,1,1 CITYWIDE ST,2080
