> There are multiple places in code where we have to check if a value is {{null}} before using it in a setter or other method, like:
> {code:java}
> if (valueX != null) {
> 	bean.setValue(valueX);
> 	someObject.compute(valueX, "bar");
> }
> {code}
> This enhancement request is to add a couple of methods in {{ObjectUtils}} to wrap this logic,  like the following:
> {code:java}
> public static <T> void applyIfNonNull(final Consumer<T> consumer, final T object)
> public static <T> void applyFirstNonNull(final Consumer<T> consumer, final T... objects)
> {code}
> With this the two statements above could be used as:
> {code:java}
> ObjectUtils.applyIfNonNull(bean::setValue, valueX);
> ObjectUtils.appyIfNonNull(v -> someObject.compute(v, "bar"), valueX);
> {code}
> The benefit of this should increase with more such null checks we need in the code that can be replaced by single statements.
> Pull request forthcoming.
