Stream find missing items on one array vs other

Manuel Antunes

difference between the list of missing entries and the origin list is:

Arrays.asList("A", "B", "C", "D", "E", "F", "G", "H") - Arrays.



  List<String> lstColonnesOrigine = Arrays.asList("A", "B", "C", "D", "E", "F", "G", "H");

  List<String> manquants = Arrays.asList("A", "B", "D",  "G");

  List<String> correspondance = lstColonnesOrigine.stream()
      .filter(colonne -> !manquants.contains(colonne))
      .collect(Collectors.toList());

  System.out.println(" différence entre liste manquants et Origine " +correspondance);
