1.Create a new project named COSC240_< your username>_Project4
2. Copy the program source files from your last project (I am assuming your last project was implemented correctly otherwise you have to start from scratch.).
3.Modify your programs based on the UML diagrams below (Song class are the same but SongList class has been modified to use ArrayList instead of array.).
4.Design a test class to test your song list. First you add a bunch of songs (at least 12) to your list; then print out all the songs in your list; after that you will call different sort methods and print out the songs after each sort method call. see image.
