I feel like there must be a better way to handle getting and processing, but I’m not seeing anything.

My code is littered with null checks immediately before “doing the thing”

Map<Integer, Animal> zoo = new HashMap();

..... Fill zoo .....

Animal a = zoo.get(id);
if(a != null) {
    a.feed(food);
}

Is there some way to better process this? Such as

zoo.getAndUse(id, animal -> animal.feed(food));
