Question

This is the program that I am trying to build.

Directions

Overall Requirements

Provide a complete program that handles the entry and display of homework scores. As part of your program, provide a YIHwScore class that contains the points earned on a particular homework and also the maximum possible points on that homework. In order to keep track of the overall average, the YIHwScore class also contains the total points earned on all homework combined and the total possible points on all homework combined. In order to determine letter grades, the YiHwScore class specifies cutoff values for the A, B, C, and D letter grades.

More specifically, the YIHwScore class should contain these constants and variables:

Array constant for the letter grade cutoffs: A = 0.9, B = 0.8, C = 0.7, D = 0.6
One dimensional array, only needs to hold the values, not the letters.
Class variables named totalEarnedPoints and totalPossiblePoints
Instance variables named earnedPoints and possiblePoints

YourNameProg2.java

Provide a main driver method. It should:

Instantiate a 4 element array of YIHwScore and store the values below in this array. In the instantiations, initialize the objects to these values:
hw1: 26.5 earned points, 30 possible points
hw2: 29 earned points, 27.5 possible points
hw3: 0 earned points, 20 possible points
hw4: 16 earned points, 20 possible points
For hw1, hw2, hw3 and hw4 call printGrade. (instance method)
Call printOverallGrade. (class method)
20%

YIHwScore.java

Within your YiHwScore class, include these requirements:

The YIHwScore class should contain a two-parameter constructor that handles initializations for the earnedPoints and possiblePoints instance variables.

Implement a printGrade method that prints a particular homework’s earned points, possible points, and letter grade. The letter grade is based on this scale: A ³ 90%, B ³ 80%, C ³ 70%, D ³ 60%, F < 60%.

Implement a class method named printOverallGrade that prints the overall earned points, overall possible points, and overall letter grade.

Use appropriate modifiers for methods. The modifiers we’ve discussed so far are private, public, and static. Use helping methods when appropriate.
60%

As always, you should:

· Limit your use of class variables and instance variables – only use them if appropriate.

· Use appropriate modifiers for your methods. The modifiers we’ve discussed are private, public, static, and final.

· Use helper methods if appropriate.

Mimic the sample session precisely.

Sample Session:

On this homework, you earned 26.5 out of 30.0 possible points: B
On this homework, you earned 29.0 out of 27.5 possible points: A
On this homework, you earned 0.0 out of 20.0 possible points: F
On this homework, you earned 16.0 out of 20.0 possible points: B
On all homework, you earned 71.5 out of 97.5 possible points: C

Here is the code that I have so far. Any help in getting the final code for the program would be greatly appreciated. If I am on the wrong track please feel free to show and explain where I am going wrong.

Driver:

public class JasonPierceProg2
{
public static void main (String[] args)
{
JPHwScore homework = new JPHwScore[4];
homework[0] = new JPHwScore(26.5, 30);
homework[1] = new JPHwScore(29.0, 27.5);
homework[2] = new JPHwScore(0.0, 20.0);
homework[3] = new JPHwScore(16.0, 20.0);
homework[0].printGrade();
homework[1].printGrade();
homework[2].printGrade();
homework[3].printGrade();
homework.printOverallGrade();
} //end main
} // end class JasonPierceProg2

Class:

public class JPHwScore
{
private double[] letterGrade = {0.9, 0.8, 0.7, 0.6};
private double[] possiblePoints; // possible points array
private double[] earnedPoints; // earned points array
private double earnedPoints; // points earned on homework
private double possiblePoints; // total possible points on homework
private double grade; // grade percentage

public JPHwScore()
{
this.earnedPoints = 0;
this.possiblePoints = 0;
} //end JPHwScore

//************************************************************
Constructor Method

public SKHwScore(double earnedPoints, double possiblePoints)
{
this.earnedPoints = earnedPoints;
this.possiblePoints = earnedPoints;
homework = new double[earnedPoints, possiblePoints];
} //end constructor

//************************************************************

public double[] getEarnedPoints()
{
return this.earnedPoints;
} //end getEarnedPoints

//************************************************************

public double[] getPossiblePoints()
{
return this.possiblePoints;
} //end getPossiblePoints

//************************************************************

Explanation / Answer

remember to change names to your name and initials public class YourNameProg2 { public static void main(String[] args) { int i; YIHwScore []hw = new YIHwScore[4]; hw[0]=new YIHwScore(26.5,30); hw[1]=new YIHwScore(29,27.5); hw[2]=new YIHwScore(0,20); hw[3]=new YIHwScore(16,20); for(i=0;i
