Reading a CSV File Into a 2D String List Using Java

Greetings, today I am here with a tutorial on how we can read the contents of a CSV file into a 2D String List using Java. By CSV, I mean a file with the csv format. This does work with .csv files but can also work with other files like .txt or .dat. This can also work with a different delimiter.

Each field of a record/line is going to get its own element in this 2D String List. A record is a collection of fields and a field is a single piece of data in a record. We store 1 record per line in this tutorial.

After we read the data from the file into a 2D String list we can then do what we want with the data, like sorting it or displaying it.

This tutorial is also great for anyone looking to read the contents of a file into a List.

Thanks for watching this tutorial on reading a csv file into a 2D String List.
