Name three examples of terminal operations in the Stream API.

In Java Stream API, terminal operations are operations that conclude the stream processing and return a result or a side effect. Three examples of terminal operations:

1. collect() — gathers stream elements into a collection or another container.

List<String> list = stream.collect(Collectors.toList());

2. forEach() — performs an action for each element of the stream.

stream.forEach(System.out::println);

3. reduce() — reduces stream elements to a single value, such as summing or concatenating.

OptionalInt sum = IntStream.of(1, 2, 3).reduce(Integer::sum);

Other examples include: count(), anyMatch(), allMatch(), findFirst().
