    Default HELP: Trying to get mp3 class to play song from playlist class

    I have created a playlist class that ask the user to enter a song name and etc. What I want to do is have the mp3 class plays the song that the user has entered, but I don't know how. Any suggestions? Thanks in advance!
    Here are my codes:

    import java.util.Scanner;
     
    public class PlaylistDriver 
    {//Start of class
       public static Playlist list;
     
       public static void main(String[] args) 
       {//Start of main
     
          list = new Playlist();
     
          while(true) 
          {
             menu();
             processInput();
          }
     
       }
     
       public static void processInput() 
       {//Start of Process Input
          Scanner keyboard = new Scanner(System.in);
          String input = keyboard.nextLine().toLowerCase();
          switch(input.charAt(0)) 
          {//Start of switch
             case 'a':
                addSong();
                break;
             case 'i':
                printSongByIndex(); 
                break;		
             case 'n':
                removeSongByName();
                break;
             case 'p':
                printSongs();
                break;
             case 's':
                getSize();
                break;
