Open the music-organizer-v1 project in BlueJ and create a Music Organizer object. Store the names of a few audio files into it-they are simply strings. As we are not going to play the files at this stage, any file names will do, although there is a sample of audio files in the audio sub-folder of the project that you might like to use. Check that the number of files returned by number Of Files matches the number you stored. When you use the list File method, you will need to use a parameter value of 0 (zero) to print the first file, 1 (one) to print the second, and so on. We shall explain the reason for this numbering in due course.
