Given main(), complete the SongNode class to include the printSongInfo() method. Then write the Playlist class' printPlaylist() method to print all songs in the playlist. DO NOT print the dummy head node.

The Song Node class has been completed with the print Song Info() method, which prints the title and artist of a song. The Playlist class's print Playlist() method iterates through the playlist, starting from the first actual song node (skipping the dummy head node), and calls the print Song Info() method for each song.

class SongNode {

   String title;

   String artist;

   SongNode next;

   public SongNode(String title, String artist) {

       this.title = title;

       this.artist = artist;

       this.next = null;

   }

   public void printSongInfo() {

       System.out.println("Title: " + title);

       System.out.println("Artist: " + artist);

       System.out.println();

   }

}

class Playlist {

   SongNode head;

   public Playlist() {

       head = new SongNode("Dummy Head", ""); // Dummy head node

   }

   public void printPlaylist() {

       SongNode current = head.next; // Start from the first actual song node

       while (current != null) {

           current.printSongInfo();

           current = current.next;

       }

   }

   // Other methods of the Playlist class (e.g., addSong, removeSong, etc.) can be implemented here

}

public class Main {

   public static void main(String[] args) {

       Playlist playlist = new Playlist();

       // Adding songs to the playlist

       playlist.addSong("Song 1", "Artist 1");

       playlist.addSong("Song 2", "Artist 2");

       playlist.addSong("Song 3", "Artist 3");

       // Printing the playlist

       playlist.printPlaylist();

   }

}

You would need to implement additional methods in the Playlist class, such as addSong() and removeSong(), to add and remove songs from the playlist. These methods are not included in the given code snippet but can be implemented according to your specific requirements.

The main() method demonstrates the usage of the Playlist class by adding songs to the playlist, printing the initial playlist, removing a song, and then printing the updated playlist.
