sorting an array and then displaying in descending order

[leoshiner]

Hi I am writing a program that will crosscheck a 2D array off a 1D array key and output the results
I have managed to output the results and now need to output them in order starting with the highest mark first
I have been partially successful in this but it will not display Student number 0 in the results.I would appreciate any
help on this,thanks

public class GradeExam2 {

    
    public static void main(String[] args) {
        char ans[][] = {{'A', 'B', 'A', 'C', 'C', 'D', 'E', 'E', 'A', 'D'},
                        {'D', 'B', 'A', 'B', 'C', 'A', 'E', 'E', 'A', 'D'},

for (int x = sortArray.length-1;x>0;x--){
-->
for (int x = sortArray.length - 1; x >= 0; x--) {


(but your results are wrong or? you are mixed some wrong together?!)

Hi just worked out that I should have x>=0 to get correct results now I just need to work out how to get it to output which number student got which results,i.e. first output
when sorted should read

Student number 4 got a count of 8 etc etc.,I supposed in order to do this I'll have to create another variable to hold the positions or something,thanks
