Comments on Project 3

This project was graded out of 20 points.

• The Tune class and its subclasses should not have any mutator methods.
• All fields must be private.
• Methods that are not part of the specification should be private.
• Don't forget to use DecimalFormat in the toString of Tune.
• Your TuneList should keep a count of the number of tunes in the array.
  Use Case Study 10 as a model.
• displayByTitle should not change the order of the list.
  It does not help to reference the list by an alias and then sort it.
  The following does not work:
       Tune[] newList = list;
       sort newList
       print newList
  Instead use:
       Tune[] newList = new Tune[tuneCount];
       copy tuneCount elements from list to newList.
       sort newList
       print newList
  
• Note that if you make newList have length tuneCount rather then list.length, you can use the sorts from class with almost no change.
• If you did not get this project working you may use the solution below as the starting point for Project 4, but you should write your own TuneTester.
