outFile and calculation probs

Submitted by theautokustomizer on Mon, 04/13/2009 - 04:00.

I have been fighting with this all day, I can't seem to get my output to come up correctly. This is what I have for now...

import java.io.*;
import java.util.*;

public class Ch7Prob14
{
public static void main(String[] args) throws FileNotFoundException
   {
//Declaring Variables
String name;
DoubleClass courseAvg = new DoubleClass();
double gradeString;
double total;
int counter;
char calculateGrade;

  //Initializing in/outFile statements   
Scanner inFile = new Scanner(new FileReader("Ch7_Ex14Data.txt"));
      PrintWriter outFile = new PrintWriter("Ch7_Ex14out.txt");

counter = 0;
gradeString = 0;
total = 0;

      //Print Headings to outFile statement
      outFile.println("Student   Test1 Test2 Test3 Test4 Test5 Average Grade");

      //Start of Loop
   while (inFile.hasNextLine())
      {
   //Initializing Variables  
name = inFile.nextLine();
      gradeString = inFile.nextDouble();   
counter++;
total = total + gradeString;


outFile.printf("%-10s", name);
        calculateAverage(inFile, outFile, courseAvg);

}

//outFile.println(calculateGrade(avg));    <----Won't work either

      outFile.close();
}

   public static void calculateAverage(Scanner inFile, PrintWriter outFile,
                                       DoubleClass cAvg)
   {
double totalGrades = 0.0;
double score = 0;

score = inFile.nextDouble();

totalGrades = totalGrades + score;

cAvg.setNum(totalGrades / 5);

}

   public static char calculateGrade(double avg)
   {
   if (avg >= 90)
   return 'A';

else if (avg >= 80 && avg <= 89)
return 'B';

else if (avg >= 70 && avg <= 79)
return 'C';

else if (avg >= 60 && avg <= 69)
return 'D';

else
return 'F';

}
}

And this is my output...

lol, now I am not getting an output...I am so tired. If anyone can help, I would appreciate it.
