Create a class MP3 with instance variables for: artist, song, album, track length (in seconds). Provide a constructor with four parameters, get/set methods, and a toString. method. The toString method should return a String with MP3 data clearly labeled. The track length should be converted into minutes and seconds in the toString method. For example, 265 seconds would be displayed as 4:25. NOTE that an MP3 cannot have a zero or negative track length. Use the default value of one minute for an invalid track length. Create a UML class diagram for the MP3 class.

Create an MP3Collection class with instance variables count and an MP3 ArrayList. The class should have a no-argument constructor, a get method for the count and a toString method that returns the information for all MP3s in the collection. The class will also have an addMP3 method that takes 4 arguments, creates an MP3 object and places it in the MP3 collection (ArrayList). Count each MP3 added to the collection. Create a UML class diagram for the MP3Collection class.

Create a test program MP3CollectionTest that adds AT LEAST 5 MP3s to the MP3 collection. Use literal data for real MP3s. The program outputs the number of MP3s in the collection and the information about all MP3s in the collection. Be sure to clearly label the output and to comment your code. Use a dialog box for output. Your name must appear in the output. Do NOT use the MP3 class in the test program.
