I have a data set represented by a Java 8 stream:

I can see how to filter it to get a random subset - for exa

Answer 1

Shorter version that uses Lombok

import java.util.function.Consumer;
import java.util.function.Predicate;

import lombok.RequiredArgsConstructor;

/**
 * Forks a Stream using a Predicate into postive and negative outcomes.
 */
@RequiredArgsConstructor
@FieldDefaults(makeFinal = true, level = AccessLevel.PROTECTED)
public class StreamForkerUtil implements Consumer {
    Predicate predicate;
    Consumer positiveConsumer;
    Consumer negativeConsumer;

    @Override
    public void accept(T t) {
        (predicate.test(t) ? positiveConsumer : negativeConsumer).accept(t);
    }
}
