you will need to add Song, PlayList and MusicPlayer classes . You will be extending the functionality of this program. You will also find songdata.txt that should go into your project. (Song, PlayList and MusicPlayer, and songdata are on the bottom)

In MusicPlayer.java:

Task 1 of 2 for MusicPlayer. Add this method :

public static void printPlayList(PlayList pl) { // see the comments in the actual code // for what the output looks like

}

Task 2 of 2 for MusicPlayer . At B: Write the missing lines of code that tokenizes a line of text from the file and creates a new Song instance. Add each song to your PlayList. Test: Print playlist after parsing the file.

In PlayList.java:

Implement these new methods:

public void playPrevSong() { // Task 1 of 7 of PlayList: This method plays the previous song

}

public int size() { // Task 2 of 7 of PlayList: return the size of the playList

ArrayList

}

public Song getSong(int i) { // Task 3 of 7 of PlayList: dont forget to test for errors

}

public Song getCurrentSong() { // Task 4 of 7 of PlayList: Return the current Son

}

public void playRandomSong() { // Task 5 of 7 of PlayList: Generate an appropriate Random number // and set the current song to it

}

public void shuffle() { // Task 6 of 7 of PlayList: Find a way to shuffle an ArrayList // Hint: Use Google or use ArrayList Javadoc // Extra credit if you do it the hard way

}

public void insertSong(Song s, int pos) { // Task 7 of 7 of PlayList: I: Implement this method // test for these conditions:

// pos < 0 add at position 0 // if pos > last index in array add to end // otherwise add at position pos using ArrayList method

}

You do not have to turn in Console output for this problem but be sure to include your modified MusicPlayer and PlayList Java files. I will run your code for this problem to see if the methods produce correct output. So I recommend that you test them before turning them in.
