How to convert a java.util.stream.Stream into an array?

Question

What would streamToArray need to do in the following code?

IntStream stream = IntStream.range(0, 3);
int[] array = streamToArray(stream); // array = [0, 1, 2]

Answer 1

IntStream has the member method toArray, that does exactly what you need:

IntStream stream = IntStream.range(0, 3);
int[] array = stream.toArray();
