Java Language Objects.nonNull() method reference use in stream api


Example

In the old fashion way for collection null check

List<Object> someObjects = methodGetList();
for (Object obj : someObjects) {
    if (obj == null) {
        continue;
    }
    doSomething(obj);
}

With the Objects.nonNull method and Java8 Stream API, we can do the above in this way:

List<Object> someObjects = methodGetList();
someObjects.stream()
           .filter(Objects::nonNull)
           .forEach(this::doSomething);
