Put value into map if not null

Question

Does Java have something like

map.putIfValueNotNull(key, value)

So I can put value in the map only if it`s not null without explicit checking.

Answer 1

I know that org.apache.commons.collections4.MapUtils contains method safeAddToMap(), but if value is null, it adds empty string which is not what you want.

I do not like variant, to override HashMap to implement new method, because in this case you do not have it for other implementations: TreeMap or LinkedHashMap or else.

I do not know about that this function exists in some availabe library, like Apache or similar.

Therefore, in my projects, I have to implement it myself:

public static <K, V> Map<K, V> addNotNull(Map<K, V> map, K key, V value) {
    if(value != null)
        map.put(key, value);

    return map;
}
