Implement a video manager. You can add videos, create playlists, generate HTML for playlists. Only Playlist.java and student test needs implementation the rest are done already

• 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.

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

Student.test - to test the methods implemented in each java

public class StudentTests {

@Test public void test() { fail("Not yet implemented"); }

}
