THIS IS A LONG QUESTION. PLEASE READ EVERYTHING IN FULL BEFORE ANSWERING. THANK YOU. An academic advisor wants a program that will compute a student GPA by reading a file that contains the name of the courses taken, credit hours for each course, and grades earned from each course. The program will take, as run-time parameters, the folder directory where the grades file is stored and the first and last name of the student. For this testing your program, use the posted grades file called grade/Irving-Whitewood.cvs. HERE IS WHAT IS IN GRADE/IRVING-WHITEWOOD.CVS:

To complete this assignment, we will use class Student.java completed from Chapter 10. The purpose for this is to reuse functionality we have already created. HERE IS STUDENT.JAVA:

import java.awt.print.Printable; import java.util.Arrays;

public class Student {

private String fname; private String lname; protected static int numCourses; Course[] cArry;

public Student() { }

//Constructors Student(String firstName, String lastName, int numCourses) { this.fname = firstName; this.lname = lastName; setNumCourses(Student.numCourses + numCourses); cArry = new Course[numCourses]; }

public void createCourse(String courseName, int creditHours, char letterGrade) { //create a course and add it to cArry Course createCourse = new Course(); createCourse.setCourseName(courseName); createCourse.setCreditHours(creditHours); createCourse.setLetterGrade(letterGrade); this.cArry[cArry.length - 1] = createCourse; }

/** * @return the fname */ public String getFname() { return fname; }

/** * @param fname the fname to set */ public void setFname(String fname) { this.fname = fname; }

/** * @return the lname */ public String getLname() { return lname; }

/** * @param lname the lname to set */ public void setLname(String lname) { this.lname = lname; }

/** * @return the cArry */ public Course[] getcArry() { return cArry; }

/** * @param cArry the cArry to set */ public void setcArry(Course[] cArry) { this.cArry = cArry; }

/** * @return the numCourses */ public int getNumCourses() { return numCourses; }

/** * @param numCourses the numCourses to set */ public void setNumCourses(int numCourses) { this.numCourses = numCourses; }

public String toString() { return "Student:\t" + fname + " " + lname; } } HERE IS COURSE:

// Class Course, revised for assignment 4.

public class Course

{

// Instance members

private String courseName;

private int creditHours;

private char letterGrade;

//Constructors

public Course()

{}

public Course(String cName, int cHours, char lGrade)

{

courseName = cName;

creditHours = cHours;

letterGrade = lGrade;

}

// Setter for courseName

public void setCourseName(String courseName)

{

courseName = courseName;

}

// Setter for letterGrade

public void setLetterGrade(char letterGrade)

{

letterGrade = letterGrade;

}

// Setter for creditHours

public void setCreditHours(int creditHours)

{

creditHours = creditHours;

}

// Getter for courseName

public String getCourseName()

{

return courseName;

}

// Getter for letterGrade

public char getLetterGrade()

{

return letterGrade;

}

// Getter for creditHours

public int getCreditHours()

{

return creditHours;

}

// Method to compute GPA for courses

public static double computeGPA(Course[] clist)

{

double gpa = 0.0;

int gradePoints = 0;

int totalCredits = 0;

for(Course c: clist)

{

int numCredits = 4;

gradePoints += c.getGradePoint() * numCredits;

totalCredits += numCredits;

}

gpa = ((double) gradePoints)/totalCredits;

return gpa;

}

// Method to convert letterGrade to a grade point numerical value

private int getGradePoint()

{

int gp = 0;

switch(getLetterGrade())

{

case 'A':

gp = 4;

break;

case 'B':

gp = 3;

break;

case 'C':

gp = 2;

break;

case 'D':

gp = 1;

break;

default:

gp = 0;

}

return gp;

}

// A way to testthe class

public static void main(String[] args)

{

Course c1 = new Course();

c1.setCreditHours(3);

c1.setLetterGrade('A');

Course c2 = new Course();

c2.setCreditHours(3);

c2.setLetterGrade('C');

Course[] clist = new Course[2];

clist[0] = c1;

clist[1] = c2;

System.out.println("GPA=" + Course.computeGPA(clist));

}

}

Inside your ComputeStudentGPAProgram.java, write a main method that serves as the main launching code. This program will read the file (grade/Irving-Whitewood.cvs) that contains the grades for a student and the first and last name of the student. The program determines the GPA for the student.

Here, you will read the csv file (grade/Irving-Whitewood.cvs) to determine the students GPA. For each line in the file, you will need store this information by calling method addCourse() from class MyStudent. Once you have completed reading the file, close the file, and then proceed to do the following:

** invoke the toString() method of this object inside a System.out.println statement

The output of your code will be:

Output: Student {firstname}, {lastname} has a {GPA value} GPA

Example: John Doe has a 3.4 GPA

NOTE

You will be provided with a file grade/Irving-Whitewood.cvs. Note that you cannot hardcode the first name and last name into your program directly. Your program MUST read the filename during the code execution.

The structure of file Irving-Whitewood.cvs is:

CourseName1,creditHours,grade

CourseName2,creditHours,grade

CourseName3,creditHours,grade

CourseName4,creditHours,grade

CourseName5,creditHours,grade

Example:

Calculus,4,A

Physics,4,A

Computer Science,4,B

English,3,C

AmericanHistory,2,B

Inside your ComputeStudentGPAProgram, you will need to use a mechanism to parse each line. While there are a variety ways to accomplish this, the String.split() method is the most feasible.
