Logging inside Stream

Question

I am trying to convert this piece of code to Java 8 stream:

if(list!=null && list.size()>0){
    Actor actor = null;
    for(Actor actor:list){

I think that using forEach in this case would be working quite nice for you? Example:

list.stream().forEach(actor -> {
    log.info(String.format("Actor being read {%s}", actor));
    String actorCode = actor.getCode();
    areaDAO.getArea(actorCode).stream().findFirst().ifPresent(area -> {
       actor.setArea(area);
       log.info(String.format("Area {%s} is fetched for actor {%s}", area, actorCode));
    });
    getContext().setReadCount(1);
})

You may want to throw in Objects.isNull() as well in some cases - e.g for that getCode part - as well as Optional.ofNullable?
