Average of N Array Element in Java

Average value of array elements would be sum of all elements/total number of elements
public class Average {
        public static void main(String[] args) {
                //define an array
                int[] numbers = new int[]{10,20,15,25,16,60,100};
                //calculate sum of all array elements
                int sum = 0;
                for(int i=0; i < numbers.length ; i++)
                        sum = sum + numbers[i];
                //calculate average value
                double average = sum / numbers.length;
                System.out.println("Average value of array elements is : " + average);
