Use the printPlaylist method to write out the data for all Song objects in your ArrayList to a separate text file in a neatly arranged format.Create at least 5 Song objects, all with valid data.Ask the user if they would like to save the playlist.If so, call the editPlaylist method and print the returned ArrayList. Ask the user if they would like to edit your playlist.Make sure to print it out in a readable format - in other words, don't just use "(playlist) " (see below for Example Output). Call the createPlaylist method, then print the returned ArrayList.Confirm to the user that the file was successfully saved, and print the filename or filepath. In the file, record the date that the playlist was saved, then write the ArrayList information to the file in a readable format - in other words, don't just use "(playlist) ". This playlist will have two parameters: the ArrayList and an indicator for whether the user would like to append to or overwrite a file.

If they choose to add a song, ask them for the song information.In this method, ask the user if they would like to add or remove a song to the playlist, or if they change their mind and don't want to add/remove any songs. An ArrayList of Song objects will be passed to this method. Create an ArrayList of at least 5 songs of your choice.
