DoubleConsumer functional interface represents an operation that accepts a single double-valued argument and returns no result. This is the primitive type specialization of Consumer for double.
The following example shows how to use DoubleConsumer
.
import java.util.function.DoubleConsumer; public class Main { public static void main(String[] args) { DoubleConsumer d = (x) -> System.out.println(x*x); d.accept(0.23); } }
The code above generates the following result.
