What does the following code print?

List<Integer> list = List.of(1, 2, 3, 4, 5); list.stream().filter(i -> i % 2 == 0).forEach(System.out::print);

⚠ Common exam trap

A common mix-up: candidates confuse the filter predicate (i % 2 == 0) with selecting odd numbers, or they forget that filter retains matching elements rather than removing them, leading to selection of option C or B.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The stream filters only even numbers (i % 2 == 0) from the list, producing 2 and 4, which are then printed sequentially via forEach. The filter operation retains elements where the predicate is true, so only 2 and 4 satisfy the condition.
