DoubleStream collect(Supplier supplier, ObjDoubleConsumer accumulator, BiConsumer combiner) example
Description
DoubleStream collect(Supplier<R> supplier,
ObjDoubleConsumer<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, ObjDoubleConsumer<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.DoubleStream;
/*w w w . ja v a 2 s. c om*/
public class Main {
public static void main(String[] args) {
DoubleStream b = DoubleStream.of(1.1,2.2,3.3,4.4,5.5);
List<Double> names = b
.collect(ArrayList::new, ArrayList::add, ArrayList::addAll);
System.out.println(names);
}
}
