Create a Student grading system. You should use a person base class (stores the name of the student). Derive a student class from the person class. The student class stores the student ID. The student class should also store the students 3 exams (Test 1, Test 2, and Test 3) and calculate a final grade (assume the 3 tests count equally). Create an array of students for a class size of 15 students. You can use the keyboard to read in all of the data for the 15 students (name, ID, and 3 grades), or read this data from a text file (PrintWriter). If using a text file, you can use Comma Seperated values (see Case study in Chapter 10 page 748 for examples how to do this), below also shows how you can read CSV (see below).

String line = "4039,50,0.99,SODA" String[] ary = line.split(","); System.out.println(ary[0]); // Outputs 4039 System.out.println(ary[1]); // Outputs 50 System.out.println(ary[2]); // Outputs 0.99 System.out.println(ary[3]); // Outputs SODA Once all the data is Imported, you can average all the exams and create a final letter grade for all students.

A - 90-100

B - 80-89

C - 70-79

D - 64-69

F < 64

The program should create an output showing all the data for each student as well as writing all the results to a file (using PrintWrite class).
