Find Intersection of Two Lists Using Java Streams

Assume two lists:

List<Integer> list1 = Arrays.asList(1, 2, 3, 4, 5);
List<Integer> list2 = Arrays.asList(3, 4, 5, 6, 7);

Using `filter()` and `collect()`

List<Integer> intersection = list1.stream()
    .filter(list2::contains)
    .collect(Collectors.toList());

System.out.println(intersection);

Output:

[3, 4, 5]
