如何从字符串数组的数组中获取Stream？

import java.util.Arrays;
import java.util.stream.Stream;

public class Main {
    public static void main(String[] args) {
        String[][] stringArray = {{"Hello", "World"}, {"Stream", "API"}};

        Stream<String> stream = Arrays.stream(stringArray)
                .flatMap(Arrays::stream);

        stream.forEach(System.out::println);
    }
}
