Stream.of(3.5, 4.7, 7.9, 8.2, 9.1, 10.5, 12.3, 15.8)
Now to Map double to int Object, use mapToObj −
.mapToInt(Double::intValue) .mapToObj(a -> "val" + a)
The following is an example to Map double to int Object with mapToInt and mapToObj −
Example
import java.util.stream.Stream; public class Demo { public static void main(String[] args) throws Exception { Stream.of(3.5, 4.7, 7.9, 8.2, 9.1, 10.5, 12.3, 15.8) .mapToInt(Double::intValue) .mapToObj(a -> "val" + a) .forEach(System.out::println); } }
