You are to create a class called MyStudent.java. This class will compute the Grade Point Average (gpa) for a given student using the formula. That is, the gpa will be computed as follows:

gpa = Total Grade Point Hours Total Possible Hours,

Total Grade Point Hours = Sum of the (Numeric Grade * Course Hours)

Total Possible Hours = Sum of the Course Hours

The input will come from a file that has the following format:

Letter Grade Course Hours

You are to change the MyStudent.java class as follows:

Create six instance variables:

totalGradePointHours

totalPossibleHours

gpa

studId // Holds Student id

fname // Holds Student First Name

lname // Holds Student Last Name

Add a Constructor:MyStudent(String inStudID, String inFName, String inLName)

The constructor receives three parameters. These parameters will be used to initialize the corresponding instance variables.

Add a MethodsloadGradeInfo(String inGrade, int inCoursehours)

This method will convert the letter grade (inGrade) to a numeric grade (i.e., A is 4.0, B+ is 3.5, etc.) and compute the earned grade point value for a course as follows:

earned grade points = Numeric Grade * inCoursehours

Then, add the earned grade points to totalGradePointHours and add the hours to totalPossibleHours.

Note: This method does not return a value.

computeGPA()

You will need to add the code to this method to compute the gpa using the following calculation:

gpa = Total Grade Point Hours Total Possible Hours

This method should update the gpa instance variable.

Note: This method does not return a value.

getGPA() : double

This is a getter method for the gpa. That is, this method will return the value of the gpa instance variable.

toString() : string

This method is called when printing is done. You will need to construct an output string (strOutput) via concatenation to produced the following output:

Student Id: 111111111

First Name: Alice

Last Name: Jones

GPA: 3.25
