Getting the mode from a data set

[javanubby]

trying to make a script that makes a list of random numbers and then outputs the mean, median, and mode of the list of numbers.
I'm currently stuck at mode part... stuck at a hash table with little to no idea how to accomplish it... any helpful hints?

public static int mode(int x[]) {
        for (int i = 1; i <= x.length - 1; i++) {
            HashSet<Integer> set = new HashSet<Integer>();
            if(set.contains(x[i]))
                ???;
            else
                set.add(x[i]);
            }
    } //end method mode

the way I'm thinking of right now would require way too many variables and just overall makes my brain hurt thinking about it.

Can you explain what "mode" is?

One item about your code. If you create a HashSet (line 3) it will be empty.
