Find the mode (most frequent value in an array) using a simple for loop?

Question

How do I find the mode (most frequent value in an array) using a simple for loop?

The code compiles with a wrong output.

Here is what I have:

Answer 1

This code is a different way that does not use hashmaps. This method, created in java, takes an array as the parameter and creates another array called "numberCount" within the method. This array "numberCount" will set its index to the value in the array. The index of "numberCount"that contains the value in the array passed will add 1 to the value of "numberCount" ("++numberCount[array[i]]") then will go to the next value in the array (repeat until the end of the array). Then creates another for loop to go through each value of the array in "numberCount", which ever index has the highest value/count will be stored and return as "max." This method will have to undergo some difficult changes to use a double array. but seems to work great with an int array.

public static int findMostFrequentValue(int[] array) {
    int i;
    int[] numberCount = new int[100];
    for (i = 0; i < array.length; i++)++numberCount[array[i]];
    int max = 0;
    int j;

    for (j = 0; j < numberCount.length; j++) {
        if (numberCount[j] > max) max = j;
    }
    return max;
}
