"for finding average : ");
final int elements = input.nextInt();;
System.out.println("");
double[] numbers = new double[elements];
double sum = 0;
for (int i = 0; i < elements; i++) {
System.out.print("Enter number "+(i+1)+" : " );
numbers[i] = input.nextDouble();
sum += numbers[i];
}
double average = sum / elements;
System.out.println("");
System.out.println("Average is " + average);
}
