Calculate Average value of Array elements

 


public class Main {
  public static void main(String[] args) {

    int[] intArray = new int[] { 1, 2, 3, 4, 5 };
    // calculate sum
    int sum = 0;
    for (int i = 0; i < intArray.length; i++){
      sum = sum + intArray[i];
    }
    // calculate average
    double average = sum / intArray.length;

    System.out.println("average: " + average);
  }
