double average= sum /numbers.length the value of average is then print .

 
public class AverageExample {
 
	public static void main(String[] args) {
  int[] numbers = new int[]{10,20,30, 40,50,}// define an array
  int sum = 0;
 
		for(int i=0; i < numbers.length ; i++) // sum the elemnt of an array
			sum = sum + numbers[i];
			double average = sum / numbers.length;
 
		System.out.println("Average value of array is : " + average);
	}
