Program: Playlist (Java)

You will be building a linked list. Make sure to keep track of both the head and tail nodes.

(1) Create two files to submit.

   • SongEntry.java - Class declaration

   • Playlist.java - Contains main() method

Build the SongEntry class per the following specifications. Note: Some methods can initially be method stubs (empty methods), to be completed in later steps.

Private fields:

   • String uniqueID - Initialized to \"none\" in default constructor

   • string songName - Initialized to \"none\" in default constructor

   • string artistName - Initialized to \"none\" in default constructor

   • int songLength - Initialized to 0 in default constructor

   • SongEntry nextNode - Initialized to null in default constructor

Default constructor

Parameterized constructor

Public member methods

   • insertAfter()

   • setNext() - Mutator

   • getID() - Accessor

   • getSongName() - Accessor

   • getArtistName() - Accessor

   • getSongLength() - Accessor

   • getNext() - Accessor

   • printPlaylistSongs()

Ex. of printPlaylistSongs output:

Unique ID: S123

Song Name: Peg

Artist Name: Steely Dan

Song Length (in seconds): 237

(2) In main(), prompt the user for the title of the playlist.

Ex: Enter playlist\'s title: JAMZ

(3) Implement the printMenu() method. printMenu() takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist. Each option is represented by a single character. Build and output the menu within the method.

If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call printMenu() in the main() method. Continue to execute the menu until the user enters q to Quit.

Ex: JAMZ PLAYLIST MENU

a - Add song

d - Remove song

c - Change position of song

s - Output songs by specific artist

t - Output total time of playlist (in seconds)

o - Output full playlist

q - Quit

Choose an option:

(4) Implement \"Output full playlist\" menu option. If the list is empty, output: Playlist is empty

Ex: JAMZ - OUTPUT FULL PLAYLIST

1. Unique ID: SD123 Song Name: Peg

Artist Name: Steely Dan

Song Length (in seconds): 237

2. Unique ID: JJ234

Song Name: All For You

Artist Name: Janet Jackson

Song Length (in seconds): 391

3. Unique ID: J345

Song Name: Canned Heat

Artist Name: Jamiroquai

Song Length (in seconds): 330

4. Unique ID: JJ456

Song Name: Black Eagle

Artist Name: Janet Jackson

Song Length (in seconds): 197

5. Unique ID: SD567

Song Name: I Got The News

Artist Name: Steely Dan

Song Length (in seconds): 306

(5) Implement the \"Add song\" menu item. New additions are added to the end of the list.

Ex: ADD SONG

Enter song\'s unique ID: SD123

Enter song\'s name: Peg

Enter artist\'s name: Steely Dan

Enter song\'s length (in seconds): 237

(6) Implement the \"Remove song\" method.

Prompt the user for the unique ID of the song to be removed.

Ex: REMOVE SONG

Enter song\'s unique ID: JJ234

\"All For You\" removed

(7) Implement the \"Change position of song\" menu option. Prompt the user for the current position of the song and the desired new position. Valid new positions are 1 - n (the number of nodes). If the user enters a new position that is less than 1, move the node to the position 1 (the head). If the user enters a new position greater than n, move the node to position n (the tail). 6 cases will be tested:

   • Moving the head node

   • Moving the tail node

   • Moving a node to the head

   • Moving a node to the tail

   • Moving a node up the list

   • Moving a node down the list

Ex: CHANGE POSITION OF SONG

Enter song\'s current position: 3

Enter new position for song: 2

\"Canned Heat\" moved to position 2

(8) Implement the \"Output songs by specific artist\" menu option. Prompt the user for the artist\'s name, and output the node\'s information, starting with the node\'s current position.

Ex: OUTPUT SONGS BY SPECIFIC ARTIST

Enter artist\'s name: Janet Jackson

2. Unique ID: JJ234

Song Name: All For You

Artist Name: Janet Jackson

Song Length (in seconds): 391

4. Unique ID: JJ456

Song Name: Black Eagle

Artist Name: Janet Jackson

Song Length (in seconds): 197

(9) Implement the \"Output total time of playlist\" menu option. Output the sum of the time of the playlist\'s songs (in seconds).

Ex: OUTPUT TOTAL TIME OF PLAYLIST (IN SECONDS)

Total time: 1461 seconds

Solution

I have implemented it inside package musicApp. You can change it if you want. And I have left it as homework for you one part. If you have problem you can ask me.
