Java Program

Suppose a student was taking 5 different courses last semester.Write a program that

(a) asks the student to input his/her name, student ID, marksfor these 5 courses,

(b) calculate the average,

(c) determine the letter grade of each course.

(d) record the number of courses whose finalletter grade is A+, A, A-, .... , F+, F, F-.

(e) Output the following information in a nice format: studentname, student ID, listing of marks, the average, letter grade foreach course, and the number of courses in each letter gradecategory.

I dont know how to do d

here is my code:

import java.util.Scanner;

public class Question_2 {

   public String Grade(int mark) {

       String GradeLetter = \"\";

       if (mark >= 93 &&mark <= 100)

           GradeLetter =\"A+\";

       if (mark >= 86 &&mark < 93)

           GradeLetter =\"A\";

       if (mark >= 80 &&mark < 86)

           GradeLetter =\"A-\";

       if (mark >= 77 &&mark < 80)

           GradeLetter =\"B+\";

       if (mark >= 73 &&mark < 77)

           GradeLetter =\"B\";

       if (mark >= 70 &&mark < 73)

           GradeLetter =\"B-\";

       if (mark >= 67 &&mark < 70)

           GradeLetter =\"C+\";

       if (mark >= 63 &&mark < 67)

           GradeLetter =\"C\";

       if (mark >= 60 &&mark < 63)

           GradeLetter =\"C-\";

       if (mark >= 57 &&mark < 60)

           GradeLetter =\"D+\";

       if (mark >= 53 &&mark < 57)

           GradeLetter =\"D\";

       if (mark >= 50 &&mark < 53)

           GradeLetter =\"D-\";

       if (mark >= 35 &&mark < 50)

           GradeLetter =\"F\";

       if (mark >= 0 && mark< 35)

           GradeLetter =\"F-\";

       return GradeLetter;

   }

   public static void main(String[] args) {

       Question_2 q2 = newQuestion_2();

       // declare variables

       String name;// student name

       studentID = input.nextInt();

       // asks the student to inputmarks of 5 different courses last semester

       System.out.println(\"Input yourcourses grade (0-100)integer number \");

       System.out.println(\"Yourcourse1's grade: \");

       mark1 = input.nextInt();
