Question

I have to write a program that reads a student’s nametogether with his or her test scores. The program should thencompute the average test score for each student and assign a grade.The grade scale is as follows: 90-100, A; 80-89, B; 70-79, C;60-69, D; 0-50, F.

The program must use the following methods:

a.       Avoid method, calculateAverage, to determine the average offive test scores for each student. Use a loop to read and sum thefive test scores. That task must be done in the method main.

b.      Avalue-returning method, calculateGrade, to determine and returneach student’s grade. (This method does not output the grade.That task must be done in the method main.)

I have to read the data from a file and send the output to afile. I cannot use any global variables.

Johnson 85 83 77 91 76

Aniston 80 90 95 93 48

Cooper 78 88 11 90 73

Gupta 92 83 30 69 87

Sample Output: The output is supposed to be inthe following form.

Student                               Test1    Test2   Test3    Test4    Test5   Average     Grade

Johnson                                85         83        77        91          76

Aniston                                 80          90         95        93        48
