How can I generate a list or array of sequential integers in Java?

With Java 8 it is so simple so it doesn’t even need separate method anymore:

List<Integer> range = IntStream.rangeClosed(start, end)
    .boxed().collect(Collectors.toList());

And in Java 16 or later:

List<Integer> range = IntStream.rangeClosed(start, end)
    .boxed().toList();
