Java: finding mode in an array

Hi, I am trying to find the mode in an array. Whenever I run the following code the mode only displays 0. The original array is ( mark[] ) it is only configured for a maximum of 10 numbers. Could some one point out to me where I went wrong?

Thanks

Code:

// create array of tallies, all initialized to zero
        int[] tally = new int[101];
        for (int i = 0; i < 10; i++) {
            tally[i] = 0;
        }

        // for each array entry, increment corresponding tally box
        for (int i = 0; i < 10; i++) {
            int value = (int) mark[i];
            tally[value]++;
        }

        // now find the index of the largest tally - this is the mode
        int maxIndex = 0;
        for (int i = 1; i < 10; i++) {
            if (tally[i] > tally[maxIndex]) {
                maxIndex = i;
            }
        }
        
        System.out.println("Mode is: "+ maxIndex);

 

The whole program is a mark-book sort of deal where you enter in the grade as a percentage for 10 students (the limit of mark[]) and the program will calculate the mode out of the 10 grades entered by the user. the percentage is between 0 and 100%. Which would be the most occurring number between 0 and 100 is what I'm looking for.
