Java Stream - 如何过滤非空值

import java.util.Arrays;
import java.util.List;
import java.util.Objects;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class Main {
    public static void main(String[] args) {
        List<String> names = Arrays.asList("Chris", "HTML", "XML", "CSS","");

        Stream<String> s = names.stream().filter(name -> name.startsWith("C"));

        List<String> collect = s.filter(Objects::nonNull).collect(Collectors.toList());
        System.out.println(collect);
    }
}
