IntStream collect(Supplier supplier, ObjIntConsumer accumulator, BiConsumer combiner) example
Description
IntStream collect(Supplier<R> supplier, ObjIntConsumer<R> accumulator,
BiConsumer<R,R> combiner) performs a
mutable reduction operation on the elements of this stream.
Syntax
collect has the following syntax.
<R> R collect(Supplier<R> supplier, ObjIntConsumer<R> accumulator, BiConsumer<R,R> combiner)
Example
The following example shows how to use collect.
import java.util.ArrayList;
import java.util.List;
import java.util.stream.IntStream;
/* w w w.jav a 2 s . c o m*/
public class Main {
public static void main(String[] args) {
IntStream i = IntStream.of(6,5,7,1, 2, 3, 3);
List<Integer> v = i
.collect(ArrayList::new, ArrayList::add, ArrayList::addAll);
System.out.println(v);
}
}
The code above generates the following result.
