Grading Assignment

[Victor]

Hello all, i am new to this community and currently enrolled in a Data Structures and Algorithms course. Java is the principle language. I am having a little trouble reading a .txt file containing grades, that is supposed to be referenced, when the user runs the program. It's supposed to show the amount of grades altogether, the AVG, MIN, and MAX, of the grades within the .txt file. I keep getting the following error when i run the program:
Please enter the text file:
examScores.txt
Exception in thread "main" java.io.FileNotFoundException: C:\Users\iMac\workspace\Grading%20Assignment\bin\e xamScores.txt (The system cannot find the path specified)

I'm not sure what you want us to do. It's telling you that it can't find that file. Is that file there? Are you absolutely sure? Check to make sure you're spelling everything correctly, including the usage of spaces.

I am having trouble with the program recognizing the .txt file. I was hoping that i may get a few ideas. It's located in the same area as my bin, src, and .settings folder for this project. And yet it doesn't open up the .txt file after typing in examScores.txt at the prompt.

Here is the src code i have:
import java.util.*;
import java.io.*;
import java.text.*;


public class Grades
{
//This method produces the heading for the program or you may say that it introduces the program.
public void introduction()
{
System.out.println("***Let's see those grades Einstein!!***");
System.out.println();
}

@SuppressWarnings("resource")
public static void main(String[] args) throws Exception
{

double sum = 0;
int gradeCount = 0;
int MAX = 0;
int MIN = 0;
double AVG = 0;
int gCount = 0;
int gCount1 = 0;
int gCount2 = 0;
int gCount3 = 0;
int gCount4 = 0;
int [] examGrades;
char letterGrade;


DecimalFormat df = new DecimalFormat("#.##");

String[] currGrades;

Scanner input = new Scanner(System.in);
System.out.println("***Welcome to the Exam Statistics Program!!***");
System.out.println();

System.out.println("Please enter the text file: ");

String txtFile = input.next();
// FileReader fr = new FileReader("C:\\" + txtFile);
FileReader fr = new FileReader(Grades.class.getProtectionDomain().getC odeSource().getLocation().getPath() + txtFile);
Scanner input1 = new Scanner(fr);

currGrades = input1.nextLine().split(" ");
input1.close();
examGrades = new int[currGrades.length];

for(int g = 0; g< examGrades.length; g++)
{
examGrades[g] = Integer.parseInt(currGrades[g]);

if (examGrades[g]<=0)
{
break;
}

gradeCount++;
sum += examGrades[g];
AVG = sum/gradeCount;

if (examGrades[g] >= 0)
{
if (examGrades[g] < MIN)
{
MIN = examGrades[g];
}
else if (examGrades[g] > MAX)
{
MAX = examGrades[g];
}


if ((examGrades[g] <= 100) && (examGrades[g] >= 90))
{
letterGrade = 'A';
}
gCount++;
if ((examGrades[g] >= 80) && (examGrades[g] >= 89))
{
letterGrade = 'B';
}
gCount1++;
if ((examGrades[g] >= 70) && (examGrades[g] >= 79))
{
letterGrade = 'C';
}
gCount2++;
if ((examGrades[g] >= 60) && (examGrades[g] >= 69))

}

{
letterGrade = 'F';
}
gCount4++;
}

}

System.out.println("The total number of grades is" + gradeCount);
System.out.println("The maximun exam score is" + MAX);
System.out.println("The minimum exam score is" + MIN);
System.out.println("The average score of the exam grades is" + AVG);
System.out.println("The number of A's is" + gCount);
System.out.println("The number of B's is" + gCount1);
System.out.println("The number of C's is" + gCount2);
System.out.println("The number of D's is" + gCount3);
System.out.println("The number of F's is" + gCount4);

}

}

But is:
C:\Users\iMac\workspace\Grading%20Assignment\bin\e xamScores.txt
the actual location of the txt file?
If not then that's the part you need to fix.
Either move the file, or change the path.

I got it, thanks. It was pointing the wrong location all along, but what i did just to be sure, was delete my examScores.txt file, then created a new .txt file named exams, and placed it within the bin directory path, and it worked. Thanks for the replies.
