General question: What’s the proper way to reverse a stream? Assuming that we don’t know what type of elements that stream consists of, what’s the generic way to reverse any stream?
Specific question:
IntStream
provides range method to generate Integers in specific range IntStream.range(-range, 0)
, now that I want to reverse it switching range from 0 to negative won’t work, also I can’t use Integer::compare
List<Integer> list = Arrays.asList(1,2,3,4);
list.stream().sorted(Integer::compare).forEach(System.out::println);
with IntStream
I’ll get this compiler error
Error:(191, 0) ajc: The method
sorted()
in the typeIntStream
is not applicable for the arguments (Integer::compare
)
what am I missing here?
