I am wondering for Lab 4 when we clear the list are we then reading the CSV file that was created in the first part of Lab 4 or are we asking the user where the CSV file is.  I think we are using the CSV file from Part 1 but I just want to make sure.

The way I did it, was when the user click on the read button, an input pop up and ask the user for the file path.

Yes, do it this way.  Think about a word processor or spreadsheet program.  You can save a document, save another document, open a different document, etc.  However, the file format is the same format you use to save, so be sure you can read the files you wrote.

use a Scanner to read from the file.  Use a JOptionPane to get the filepath and file name to read from or write to.
