File input and output - Basic Java Fast (38)

The video demonstrates the file input and output approaches for Java. To read from a text file, we generate a File object, and then connect it to a Scanner object which reads text. When reading from a file, we have to handle the exception of failing to find the file. We also create objects using the PrintWriter class to write text to a text file.

You'll learn most by trying my code while watching the video.
