In this video, I introduce the concept of storing information in text file format. I create some data that represents a shopping list using an ArrayList and write the data to a file called shopping.txt using the Java FileWriter and PrintWriter classes. I then write a method to read the information back from the shopping.txt file using the FileReader and BufferedReader classes.
