• From a collection of object that return an exit status

Integer errors = insertStreamListeners
                .stream()
                .mapToInt(s -> s.getExitStatus()>0?1:0)
                .sum();

• Where myMao is map where the values are integers

Integer tot = myMap
    .values()
    .stream()
    .mapToInt(s->s)
    .sum()
