Implement yet another DataSetGeneric class without using any JCF classes. See LabStarterCode elsewhere in this Lesson. There are six or seven valid approaches to solving this problem. You are free to use any of them. You may have to make one compromise in DataSetGeneric's specification; the add method for DataSetGeneric returns a boolean indicating that the add worked. The classes of this chapter specify add as void. Your solution should return a boolean, but it can always return true if you choose to use a class from this chapter.
