Counting characters example in Ignite in Java8

Collection<String> words = Arrays.asList("How Many Characters".split(" "));

// Each closure is given a single word and returns the word's length.
// Each closure will be executed on a different cluster member.
Collection<Integer> res = ignite.compute().apply(String::length, words);

int sum = res.stream().mapToInt(Integer::intValue).sum();

Here is the full version:

--------
try (Ignite ignite = Ignition.start()) {
  Collection<String> words = Arrays.asList("How Many Characters".split("
"));

  // Each closure is given a single word and returns the word's length.
  // Each closure will be executed on a different cluster member.
  Collection<Integer> res = ignite.compute().apply(String::length, words);

  int sum = res.stream().mapToInt(Integer::intValue).sum();

  System.out.println("Total number of characters is '" + sum + "'.");
}
