        System.out.println("The class average test score is " + decimalPlace.format((double) (total)/ count) + ".");
        System.out.println("The highest score is " + maxGrade + ".");
        System.out.println("The lowest score is " + minGrade + ".");
        System.out.println("The number of students who passed is " + passed + ".");
        System.out.println("The number of students who received an A is " + gradeA + ".");
        System.out.println("The number of students who received an B is " + gradeB + ".");
        System.out.println("The number of students who received an C is " + gradeC + ".");
        System.out.println("The number of students who received an D is " + gradeD + ".");
        System.out.println("The number of students who received an F is " + gradeF + ".");
    }
}

This is my code and I am importing a file and need to print out the number of students in the class, the average test score, the highest and lowest grade, and how many received each letter grade. I will attach the text file I imported.
My output says there is only 33 students and there should be 35. It was outputtingGrades.txt 35 before I put in all the if statements to add to the number of each grade. Then it changed to 33 and I'm not sure how to fix it.

Your problem is here:

maxGrade = scan.nextInt ();
minGrade = scan.nextInt ();

The counter is not increased for the first two lines you read. I would set the maxGrade to 0, and minGrade to 100, then remove those two lines.

Post retracted. Good advice already given..
