How do I add an item to a String array of type List?

Question

In my code, I am reading in a text file using CSVReader and putting all that into a String array of type list:

CSVReader reader = new CSVReader(new FileReader("addTest.txt"), ',');
List<String[]> myEntries = reader.readAll();
reader.close();

I'm now wanting to add an item to the list, however, when trying to do this via myEntries.add("test" + "," + "test2"), it does not accept it. My goal here is to add an item or items to a new line, then I will use CSVWriter to write it back to file.

How do I go about adding an item, or items to a string array of type list? I've looked around but this problem still has me stumped.

Thank you.

Try adding items to an array. Then just add the whole array to the list. — Elroy Jetson

The List takes a String array not a comma delimitered string. Can add as

myEntries.add (new String [] {"test", "test2"});
