How Can I use Java Stream To Build a List<Integer> And The Integer Between a and b

Question

Say I have two variables : a = 5, b = 8,

And I want :

Arrays.asList(5, 6, 7, 8)

How Can I Use Java stream To get this?

Answer 1

you can use IntStream.rangeClosed to generate the numbers and collect into a list.

List<Integer> result = IntStream.rangeClosed(a, b)
                                .boxed()
                                .collect(Collectors.toList());
