# intersection method

Set<E> intersection(

1. Set<Object?> other

)
override

Creates 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`.

    final characters1 = <String>{'A', 'B', 'C'};
    final characters2 = <String>{'A', 'E', 'F'};
    final intersectionSet = characters1.intersection(characters2);
    print(intersectionSet); // {A}

## 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;
    }
