Beginner Problem: Array sorting decreasing element values? Why?

Code :

```public class GradeExam { public static void main(String[] args) { char [][] answers = { {'A', 'B', 'A', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}, {'D', 'B', 'A', 'B', 'C', 'A', 'E', 'E', 'A', 'D'}, {'E', 'D', 'D', 'A', 'C', 'B', 'E', 'E', 'A', 'D'}, {'C', 'B', 'A', 'E', 'D', 'C', 'E', 'E', 'A', 'D'}, {'A', 'B', 'D', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}, {'B', 'B', 'E', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}, {'B', 'B', 'A', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}, {'E', 'B', 'E', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}};   char[] keys = {'D', 'B', 'D', 'C', 'C', 'D', 'A', 'E', 'A', 'D'};   int[] ArrayF = new int[8]; for (int i = 0; i < answers.length; i++) { int correctCount = 0; for (int j = 0; j < answers.length; j++) { if(answers[i][j] == keys[j] ) correctCount++; } ArrayF[i] = correctCount; } for (int a = 0; a < ArrayF.length - 1; a++) { int currentMin = ArrayF[a]; int currentMinIndex = a; for (int b = a + 1; b < ArrayF.length; b++) { if (currentMin > ArrayF[b]) { currentMin = ArrayF[b]; currentMinIndex = b; } } if (currentMinIndex != a) { ArrayF[currentMinIndex] = ArrayF[a]; ArrayF[a] = currentMin; } } for (int k = 0; k < ArrayF.length; k++) { System.out.println("Student " + (k+1) + "'s correct count was " + ArrayF[k]); } } }```

Bonus question: How would I go about sorting the student number too?

Quote:

when I call on them to be printed out, they are -2 than what their value should be.
Can you show the print out or other evidence where this is shown?
Post the program's output and explain what is wrong with it and show what it should be.
