Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

public class Javaexcercise {
public static void main(String[] args) {   
 
       int[] numbers = new int[]{10, 20, 30, 60, 80, 100};       
       int sum = 0;
       for(int i=0; i < numbers.length ; i++)
        sum = sum + numbers[i];
       //calculate average value
        double avg = sum / numbers.length;
        System.out.println("Average value of the array elements is : " + avg); 
   }
}

Result
