Reading a CSV File Into a 2D String Array Using Java
Reading a CSV File Into a 2D String Array 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 array 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 array. 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 array, we can then do what we want with the data, like sorting it or displaying it.
You can easily change this tutorial to store the data in a multidimensional list, a custom class/data structure system or even a regular String array. I am covering 2D String arrays because of a YouTube comment request and so this video can be a direct follow up.
