# intersection method Null safety

Set<E> intersection (

1. Set<Object?> other

)
override

Returns a new set which is the intersection between this set and `other`.

That is, the returned set contains all the elements of this Set that are also elements of `other` according to `other.contains`.

## Implementation

    Set<E> intersection(Set<Object?> other) {
      Set<E> result = toSet();
      for (E element in this) {
        if (!other.contains(element)) result.remove(element);
      }
      return result;
    }
