Using a foreach(for each) for loop with a collection.


import java.util.ArrayList;

public class MainClass {
  static double getAvg(ArrayList<Double> nums) {
    double sum = 0.0;

    for (double itr : nums)
      sum = sum + itr;

    return sum / nums.size();
  }

  public static void main(String args[]) {
    ArrayList<Double> list = new ArrayList<Double>();

    list.add(10.14);
    list.add(20.22);
    list.add(30.78);
    list.add(40.46);

    double avg = getAvg(list);

    System.out.println("List average is " + avg);
