Lab Steps Step 1: StudentGPAInfo (20 points) You will create a class to store information about a student's courses and calculate their GPA. Your GPA...

Hi,

I have question concerning a homework problem in CIS 355A. I am coding a program in JAVA that will calculate the student GPA and output the student's name and their GPA. This what I have so far.

import java.util.Scanner;public class StudentGPAInfo{        private String studentName;        private String grade;        private String credits;

        public StudentGPAInfo()//Default Constructor        {            studentName= "Not set";            grade = "Not set";            credits = "Not set";        }                public void setStudentName(String studentName)         {             this. studentName = studentName;        }                        public void addClass(String grade, double credits)         {            //Grade is equal to gradePoints            double points = 0;            double gradePoints;            double GPA;                                    if( grade == "A" || grade == "a")             points = 4.0;            else                if(grade == "B" || grade== "b")                points = 3.0;                else                     if (grade == "C" || grade == "c")                        points = 2.0;                    else                        if (grade == "D" || grade == "d")                            points = 1.0;                        gradePoints= points * credits;            GPA = gradePoints /credits;                    }        public double getGPA()        {            return GPA;        }        public void displayStudent ()    {            System.out.println(studentName + ", your GPA is " + String.format("%.2f", GPA));    }    public static void main(String[] args)     {            StudentGPAInfo student = new StudentGPAInfo();            Scanner sc = new Scanner(System.in);                        // Prompt for student name and set it.            System.out.print("Enter student name:  ");            String studentName = sc.nextLine();            student.setStudentName(studentName);            String another = "y";            do            {                System.out.print("Enter class credits:  ");                double credits = sc.nextDouble();                System.out.print("Enter letter grade:  ");                String grade = sc.next();                student.addClass(grade, credits);                                System.out.print("Another class?  (y/n) ");                another = sc.next();            } while (another.equalsIgnoreCase("Y"));            sc.close();                        // Call student.displayStudent() to show results.            student.displayStudent();    }    }I have also attached the document for the assignment which gives you the instructions of how to format the code for the program.
