Running Java Program in Eclipse multiple times

I wrote a Java program in Eclipse that uses Processing IDE libraries, and it works just fine. This program gets some data from a .csv file and assign those values to the variables inside the program.

I want to make this program run multiple times automatically and sequentially, and before each run I want to modify some of the data from the .csv file so that I can get different outputs at each time.

I've been thinking about this for a long time and couldn't come up with any answer myself. Any help will be appreciated.

Thanks, Mert
