Question

Create a Gradekeeper class. The sort method in this class will sort an array of grades that is passed to it in descending order. The array of names should be re-ordered according to the re-ordering of the grades array.
HINT: The sort method can use the code from InsertionSort to sort the grades array. Whenever the sort routine exchanges elements of the grades array, it should also exchange the corresponding elements of the names array.
Once you have the GradeKeeper class working properly, write your own main program that reads at least 4 grades and 4 names from the user. It should then sort these values using the GradeKeeper class and then print the names and grades.
