Curious :
First statement works but not second giving below error, why ?
java.util.Arrays.asList(1,2,3,4,5).stream()
.map(n -> n+1)
.collect(Collectors.toList());
List<Integer> list = IntStream.rangeClosed(1, 10)
.map(n -> n + 1)
.collect(Collectors.toList());
ERROR:
Type mismatch: cannot convert from Collector<Object,capture#5-of ?,List<Object>>
to Supplier<R>
Joe C :
While there is a collect method on a Stream which accepts a Collector, there is no such method on an IntStream.
You can convert your IntStream to a Stream<Integer> using the boxed() method.
