       int[] numbers = new int[]{20, 30, 25, 35, -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 the array elements is : " + average); 
   }
}
