Ok so here's the code my friend and I have made so far

Basically what I need know is how to replace those underscores with the grades that each student got on the test out of 10. (ie if they get 7 out of 10 then they recieve a C on it, using A B C D, and F for failure)Code:

/**

* @(#)miatasGroup.java

*

* miatasGroup application

*

* @author

* @version 1.00 2011/1/29

*/

import java.io.*;

import java.util.StringTokenizer;

public class miatasGroup {

private static FileInputStream inFile;

private static InputStreamReader inReader;

private static BufferedReader reader;

public static void main(String[] args) throws IOException {

initFile();

getData();

inFile.close();

}

public static void initFile() throws IOException {

String locationFile = new File("TestSheet.txt").getAbsolutePath();

inFile = new FileInputStream (locationFile);

inReader = new InputStreamReader(inFile);

reader = new BufferedReader(inReader);

}

public static void getData() throws IOException {

String line = reader.readLine();

StringTokenizer strTkn;

strTkn = new StringTokenizer(line);

String answer = strTkn.nextToken();

System.out.println("The answers for the test are as follows: " + answer + " T standing for True, and F standing for False.");

System.out.println("-----------------------------------------------------------------------------------------------------");

String answerKey = line;

StringTokenizer tokens;

while((line = reader.readLine()) != null) {

int total = 1;

int counter0 = 0;

int counter1 = 0;

int counter2 = 0;

int counter3 = 0;

int counter4 = 0;

int counter5 = 0;

int counter6 = 0;

int counter7 = 0;

int counter8 = 0;

int counter9 = 0;

int[] studentID = {1, 2};

String[] studentAnswers = {"a", "b"};

tokens = new StringTokenizer(line);

studentID[total] = Integer.parseInt(tokens.nextToken());

studentAnswers[total] = tokens.nextToken();

total++;

if (studentAnswers[1].charAt(0) == 'T'){

counter0 = counter0 + 1;

}else{

}

if (studentAnswers[1].charAt(1) == 'T'){

counter1++;

}else{

}

if (studentAnswers[1].charAt(2) == 'T'){

counter2++;

}else{

}

if (studentAnswers[1].charAt(3) == 'T'){

counter3++;

}else{

}

if (studentAnswers[1].charAt(4) == 'T'){

counter4++;

}else{

}

if (studentAnswers[1].charAt(5) == 'T'){

counter5++;

}else{

}

if (studentAnswers[1].charAt(6) == 'T'){

counter6++;

}else{

}

if (studentAnswers[1].charAt(7) == 'T'){

counter7++;

}else{

}

if (studentAnswers[1].charAt(8) == 'T'){

counter8++;

}else{

}

if (studentAnswers[1].charAt(9) == 'T'){

counter9++;

}else{

}

int numberscorrect = (counter0 + counter1 + counter2 + counter3 + counter4 + counter5 + counter6 + counter7 + counter8 + counter9);

System.out.println("Student number: " + studentID[1] + " Answered " + numberscorrect + " Correctly out of 10, and recieved a grade of: " + "__ " + "With the answers: " + studentAnswers[1]);

}

}

}

Output:

The answers for the test are as follows: TFFTFTTFTT T standing for True, and F standing for False.
