How to return values from methods that contain arrays in parameters in Java?

I have this code, but it doesn't work!

public class Trial
{
    public static void main (String [] args)
    {
        int average;
        int m = 0;

        int [] nums = {1,6,8,9,10,60,72};

        average = getAverage(int [] nums);
    }

    public static int getAverage(int [] a)
    {
        int sum = 0;
        for(int i=0; i<a.length; i++)
            sum = sum +a[i];

        int avg = sum/a.length;
        return avg;
    }
}

What's the problem? I need to get the average of the array by calling the method of calculating the average

Solution

Change method call:

average = getAverage(nums);
