i need help with this code

Statistics are often calculated varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. When the input is 15 20 0 5 -1, the output is 10 20. You can assume that at least one non-negative integer is input.

I see...

So, this is a textbook (or otherwise) problem from outside of Treehouse, and you're looking for some kind of assistance in writing the program?

This should get you going. This only provides the average; you'll need to reason out how to get the max value.

public static double getAverage(int[] array)
{
    int sum = 0;
    for(int i : array) sum += i;
    return ((double) sum)/array.length;
}
