outFile and calculation probs

[autokustomizer]

Hello again all. I am back with another issue, haha. I have created a document to read from, 10 names with 5 grades each, one line per person. I need have that information come back up under my headings, added, and averaged. I think what I have should work, it compiles and executes, but not correctly. How do I get it to come up as a one line each and the average. I also need an 'A', 'B', etc... to come up with the corresponding grade. This is what I have....

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.hasNext())
      {	
   		//Initializing Variables   	
			name = inFile.next();
      	gradeString = inFile.nextDouble();    
			counter++;
			total = total + gradeString;
			
				
			outFile.printf("%-10s \n", name);
     	   calculateAverage(inFile, outFile, courseAvg);
			 
		}

//		outFile.print(calculateGrade);   <---This line won't compile or execute   
	
      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 how it comes up....

Student Test1 Test2 Test3 Test4 Test5 Average Grade
Johnson

Aniston
95
Cooper
11
Gupta
30
Blair
96
Clark

What is wrong with my code?
