Description

I have a new suggestion about null handling.

I usually check a object is null or not before using it to avoid NPE.

It is pretty obvious, but It is quite cumbersome and has some overhead.

So I want to introduce the following null-safety methods in ObjectUtils class and make people easy to handle null without using if/else statement or Optional class, etc.

public static <T, R> R applyIfNotNull(final T object, final Function<T, R> function) {
    return object != null ? function.apply(object) : null;
}

public static <T> void acceptIfNotNull(final T object, final Consumer<T> consumer) {
    if (object != null) {
        consumer.accept(object);
    }
}

What do you think about it?

If it looks good, I will implement this feature.
