A first algorithm

Introduction

An algorithm is a repeatable procedure for solving a problem. Counting values is one example: begin with zero, inspect each item, and update the count when it matches. Check the empty collection and a collection with no matches.

public class Main {
  public static void main(String[] args) {
    int[] numbers = {2, 5, 8, 11, 14};
    int count = 0;
    for (int number : numbers) {
      if (number % 2 == 0) count++;
    }
    System.out.println(count);
  }
}
