Implement a video manager. You can add videos, create playlists, generate HTML for playlists, etc. In the code distribution we have included a driver (SampleDriver.java) and expected output (SampleDriverOutput.txt) that illustrates some of the functionality provided by the system.

Fill in the empty methods to add videos, create playlist and generate HTML for playlist in Playlist.Java and also Video.Java

• tubeVideosManager A package where you will find shells for classes you need to implement.
• tests A package where you will find public tests and a shell file for student tests.
• text files/directories Files providing input for public tests, and support directories will be found in the main project folder. Expected outputs for public tests will be found in the expectedResults folder. Results generated by your code when you run your public tests will be placed in the results folder.

Method Descriptions are below

Genre.java

public enum Genre { Comedy, Educational, Documentary, Music, FilmAnimation }

Playlist.java

public class Playlist { private String name; private ArrayList videoTitles;

/** * Initializes playlist with the specified name and creates an empty ArrayList.

TubeVideosManager.java Thank you for your help if you are confuse you can comment to let me know i will thumbs up. Here is my email taphlawolf at g mail .com i can send any file you need to you. some of the files i cant provide because of limits line space. Can You comment a email address for me to send the SampledriverOutput.txt file. I also would like to ask future question as well if i need help
