Create an IntStream and a Stream<Integer> from an Eclipse Collections IntList/IntIterable

Question

I have an Eclipse Collections IntList. How can I

1. Create a Java IntStream from this list
2. Create a Java Stream<Integer> from this list

without copying the elements?

Answer 1

With Eclipse Collections 10.0 you can now call primitiveStream directly on IntList.

IntStream intStream = IntLists.mutable.with(1, 2, 3, 4, 5).primitiveStream();

Stream<Integer> stream = intStream.boxed();
